Why is pH an intensive property?
Answers
Answer:
As the pH is the measure of concentration of H+ ions and as concentration is an intensive property so pH is also an intensive property. It's intensive as it is mass independent. pH means negative log of concentration of hydroniun ions in the solution
Explanation:
Answer:
pH is an INTENSIVE property as it does not depend on the amount of material present. The pH of 1 ml of solution x is the same as the pH of 100 ml of solution x.

Explanation:being that there are many species of cat that prolly come from one organism they all evolved according to there needs
The idea of evolution is one explanation for the similarities between living things and extinct ones, such as the Smilodon saber-toothed tiger and contemporary cats. Through the processes of natural selection, genetic drift, and gene flow, populations of species undergo evolution over time.
What is an Evolution?Natural selection, genetic drift, and gene flow are three processes that allow populations of organisms to change over time. This process is known as evolution.
When populations of organisms diversify and some individuals have traits that are more beneficial to their environment than others, evolution occurs. This causes the evolution of new species over time that are more adapted to their surroundings.
For example, the evolution of modern cats from the Smilodon saber-toothed tiger probably occurred over a long period of time through a succession of small changes in the cat population. Eventually, the evolution of the contemporary cat was influenced by cats that had somewhat sharper teeth or a greater hunting ability because they were more successful at catching prey and passing on their genes.
Therefore, the idea of evolution is one explanation for the similarities between living things and extinct ones, such as the Smilodon saber-toothed tiger and contemporary cats.

Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

which source of renewable enegry do you think is most likely to be used in your community within the next 20 years? explain your answer
Answers
In recent years, there has been a significant shift towards renewable energy sources in many countries, as they are becoming more cost-effective and environmentally friendly compared to traditional fossil fuels. The most common renewable energy sources are solar, wind, hydroelectric, geothermal, and biomass.
Solar energy is one of the most rapidly growing renewable energy sources worldwide. It has already become affordable for households and businesses to install solar panels, which are increasingly being used to generate electricity. In many communities, solar farms are also being established to supply power to the grid. With the advancement in technology, the efficiency of solar panels is improving, and the cost of installation is decreasing, making it a more viable option for more households and businesses.
Wind energy is another renewable source that is increasingly being utilized. Wind turbines are being installed in many areas, especially in regions with consistent winds. As with solar energy, advances in technology are leading to improved turbine efficiency and lower installation costs.
Hydroelectric energy is a well-established source of renewable energy that has been in use for many years. Many countries have already established hydroelectric power plants, and more are being constructed. While the construction and operation of these plants can have some environmental impacts, hydroelectricity is a clean and reliable source of energy.
Geothermal energy is another renewable source that has great potential. It involves extracting heat from the earth's core to generate electricity. While currently geothermal energy is not widely used, there is increasing interest in it as a source of clean and renewable energy.
Biomass energy involves using organic materials such as wood chips, crop waste, or even animal manure to generate electricity. While this source of energy is not as clean as some of the others, it can be a good option for communities that have access to a lot of biomass waste.
In conclusion, the most likely source of renewable energy to be used in a community will depend on a variety of factors, including the availability of resources, local government policies, and technological advancements. However, solar and wind energy are likely to become more popular due to their increasing affordability and efficiency, as well as their potential for use at a household or small business level.
Answer: Electricity is the renewable energy source likely to be used within the next 20 years.
Explanation:
These days electricity is reaching far and wide corners of the country, with this fast growth the future is electric. The growing craze for electric cars, electric cars, and other electrical appliances electricity demand is increasing.
Electricity is easy to produce with the use of hydropower plants and windmills. It is most likely to take over the future.

Mechanical energy can take on many forms, but these different forms can be categorized as either potential energy or energy of motion. The height an object is dropped from has an effect on the amount of energy in the object. Let’s conduct an experiment to see the effect.
:How does the height of an object affect the amount of mechanical energy it contains?
1:Variables What is the test variable?
Answers
The height of an object is crucial to the amount of energy something has because the higher up it is the most potential energy it has and kinetic energy it could have.
For example, if the height of a basketball was just a couple inches off the ground, it would not have a large amount of potential energy because because there is not much of a fall between the ball and the ground. However, if the ball was higher, there would be more potential energy because there is more room to fall.
---
"What is the test variable?"
The test variable, or independent variable in this case would be the height, as the scientist is changing the height in order to get different results in the total mechanical energy, which would be the dependent variable.

If the "A" represents red flowers and "a" represents green glowers, what are the chances of the flowers being green?
Answers
Answer: 50%.
Explanation:
The A allele, which corresponds to red flowers is dominant, meaning if one is present, the flower is red. This generates Aa, which matches 2 squares, denoting a 50% in 4 total boxes. The a allele, corresponds to green flowers but is recessive, meaning both alleles must correspond to said trait to be expressed. 2 squares fit this scenario, making another 50% chance. Therefore, the answer would be 50%.
if you look at the table there is
Parent one: one dominant gene parried with a recessive gene
Parent two: two recessive genes
Any time this combination happens it will always be 50%
