When water vapor is cooled, it re-forms into water droplets. Why does this represent a conservation in mass?
50 POINTS!!!
Answers
Answer:
People, especially kids, tend to think that when water evaporates it just disappears, or turns into the air. But we know based on the law of conservation of mass that any time water changes state it keeps the same mass!
Similarly, when water vapor turns to water droplets, when it goes from its gas to its liquid state, it still has the same mass. It's just in a different phase. This is a perfect example of conservation in mass!

The water of a swimming pool is hypotonic to our cells. Explain in detail with evidence and reasoning why we do not swell and pop when we go for a swim.
Answers
Answer: Hello: ) ✨ It depends on the concentration of all solutes in the solution (ie, its osmolarity). A solution with low osmolarity is hypotonic and vice versa. Solutions having the same osmolarity are isotonic. Water in pools and rivers is hypotonic compared with sea water, but water from the Dead Sea is hypertonic.We do not swell and pop when we go swimming in a hypotonic swimming pool because our skin protects us from the external environment and does not let water cross into or out of our body surfaces. ... hope this helps have a great dayAssuming the water is warm enough that you don’t simply die of hypothermia, the next problem would be your skin. For reasons that still aren’t well understood, human skin starts to break down after continuous immersion in water of a few days. You’d suffer open sores and be liable to fungal and bacterial infections just from the spores on your skin, even if the water itself was perfectly sterile. The pressure of the water also reduces the circulation to your extremities and makes breathing more difficult.
Explanation:
A relative term, hypotonicity defines a solution's characteristic in relation to another solution.
What is hypotonic solution?The cytosolic fluid or the fluid found inside a cell is frequently used as the comparison solution in biology. Therefore, a solution would be considered hypotonic in biology if it contained fewer solutes than the cytosol of a cell. The semipermeable membrane is the cell membrane. What then occurs to a cell in a hypotonic environment.
Tonicity has the prefix "hyper," which denotes "more" or "excess." Consequently, a solution that contains more non-penetrating solutes than the other solution can pass through a semipermeable barrier.
Therefore, A relative term, hypotonicity defines a solution's characteristic in relation to another solution.

Question:
which has more calories : table sugar or aspartame ?
Answers
Table sugar, also known as sucrose, contains 4 calories per gram, whereas aspartame contains only 0.2 calories per gram. This makes table sugar much higher in calories than aspartame.
Answer:
Table sugar has more calories than aspartame. A teaspoon of table sugar (4 grams) contains approximately 16 calories, while a teaspoon of aspartame (0.5 grams) contains only 0.4 calories. This is because table sugar is a carbohydrate and contains four calories per gram, while aspartame is a non-nutritive sweetener and is virtually calorie-free.

What happens to air pressure and amount of oxygen as the altitude increases in Earth's atmosphere? 1. Air pressure decreases, while the amount of oxygen increases. 2. Both air pressure and the amount of oxygen increase. 3. Air pressure increases, while the oxygen decreases. 4. Both air and oxygen decrease.
Answers
Answer:
As altitude increases in Earth's atmosphere, both air pressure and the amount of oxygen decrease.
At sea level, the air pressure is about 1013.25 millibars (mb) and the concentration of oxygen is about 21%. As you go higher in the atmosphere, the air becomes thinner and less dense, so the air pressure decreases. At the same time, the concentration of oxygen also decreases because there is less air overall to contain oxygen molecules.
This is why it is harder to breathe at high altitudes, such as on a mountain. The air is less dense, so there are fewer oxygen molecules per breath and the body has to work harder to get enough oxygen.
Answer:4: Both Air and Oxygen decrease.
Explanation:This is in accordance with Henry's law. As pressure decreases solubility of gases decreases. Air pressure decreases as we altitude increases and the decrease in oxygen level is the consequence ,

2. it is a cold current in the pacific ocean
3. it carries warm water from the americans to western europe
4. it moderates the climate of western europe
5. it makes westerns europes climate more harsh
Answers
The three correct options are:
1. It is a warm current in the Atlantic Ocean.
3. It carries warm water from the Americas to Western Europe.
4. It moderates the climate of Western Europe.
The Gulf Stream is a warm and swift ocean current in the Atlantic Ocean, originating in the Gulf of Mexico and flowing northeastward along the eastern coast of the United States and Canada. It carries warm waters from the tropics towards the North Atlantic region, including Western Europe.
As it moves across the ocean, it helps to moderate the climate of Western Europe by releasing heat, thereby making the winters milder and the overall climate more temperate. The Gulf Stream plays a crucial role in influencing the weather patterns and maintaining a relatively mild climate in Western Europe compared to other regions at similar latitudes.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
