Answer:

True

Explanation:

The greenhouse effect is a natural process that occurs when certain gases in the atmosphere, such as carbon dioxide and water vapor, trap heat from the sun. This keeps the Earth's temperature within a range that is suitable for life. However, an increase in the amount of greenhouse gases, such as from human activities like burning fossil fuels, can intensify the greenhouse effect and lead to global warming. This warming can have a range of impacts on the environment, such as melting ice caps, rising sea levels, and more frequent and severe weather events.

From the question, the point at which the heating curve does plateau is the boiling point of water.

The heating curve is used tool that we use to see how the temperature change by the addition of heat affects the state of matter in which the material is obtained. The vertical axis could be used to plot the temperature while the horizontal axis could be used to plot the changes in the state of matter.

There are three states of matter namely;

Liquid

Solid

Gas

Water can be able to exist in all the states of matter that have been mentioned but there is a temperature range at which each state of matter can be observed. Thus we have the solid range, liquid range and the gaseous range of water.

Looking at the graph, when we begin to heat the water, the water is liquid at the start but the temperature increases rapidly. This increase would continue until the temperature  of the water begins to plateau. The point of plateau is the boiling point of water.

This state at a specific temperature is called phase change.

For example, evaporization is phase change process in which the water changes from a liquid to a gas (water vapor).

Other example, condensation is phase change process in which the water changes from a gas to a liquid.

Heating curve of water show how the temperature changes as water is heated up. A heating curve for water that shows transition zones (see the picture below).

The first phase change is melting, the temperature stays the same while an ice melts.

The second phase change is boiling, the temperature stays the same while a water boils.

Based on the graph, the reaction with a linear decrease in concentration is the first-order reaction, while the reaction with a curved decrease is the second-order reaction.

In a first-order reaction, the concentration of the reactant decreases exponentially with time, resulting in a straight line on a graph of ln(concentration) versus time. Therefore, to make the plot of the first-order reaction linear, we need to plot ln(concentration) on the y-axis.

In a second-order reaction, the concentration of the reactant decreases at a rate proportional to the square of its concentration, resulting in a curved line on a graph of concentration versus time. To make the plot of the second-order reaction linear, we need to plot 1/concentration on the y-axis.

By transforming the y-axis to ln(concentration) for the first-order reaction and 1/concentration for the second-order reaction, we can observe linear relationships between the transformed y-axis and time for both reactions.

a) The smoke obscuration meter provides a measurement of smoke obscuration, which is defined as the reduction of transmitted light caused by smoke particles in the air.

The corresponding optical density can be calculated using the formula: optical density = -log(T), where T is the transmittance. In this case, the transmittance is 1 - 0.4 = 0.6. Therefore, the optical density is -log(0.6) = 0.221.

The extinction coefficient is a measure of how strongly the smoke particles scatter or absorb light, and can be calculated using the formula: extinction coefficient = optical density / distance. In this case, the distance between the light source and the detector is 4.0 m. Therefore, the extinction coefficient is 0.221 / 4.0 = 0.055.

b) The visibility of a light emitting sign subjected to such an environment can be calculated using the formula: visibility = e^(-kL), where k is the extinction coefficient and L is the path length of the light through the smoke.

In this case, we do not know the path length of the light through the smoke, so we cannot calculate the visibility.

The mass of ZnCl2 is 52.4 g

The mass of NH3 is 12.24 g

Realizing that

Zn has a number of moles of 25 g/65 g/mol.

= 0.385 mole

In the event when 1 mole of zinc produces 1 mole of zinc chloride

Thus, 0.385 moles of ZnCl2 are produced.

A mass of 0.385 mole * 136 g/mol ZnCl2 is generated.

= 52.4 g

2) 10g/28 g/mol, or 0.36 moles, is the formula for N2's moles.

For number of moles of H2; 60 g/2 g/mol

= 30 moles

One mole of N2 reacts with three moles of H2,

0.36 moles interact with N2 at a rate of 0.36 * 3/1.

= 1.08 moles

Therefore, N2 is the limiting reactant.

From 1 mole of N2, 2 moles of NH3 are created.

The answer is 0.36 * 2/1 for 0.36 moles of N2.

= 0.72 moles

Mass of NH3 =  0.72 moles * 17 g/mol= 12.24 g

The total cooling performed by the coil is 29168.21 BTU/Hr and the sensible cooling performed by the coil is 1209.93 BTU/Hr.

Inlet Condition: TDB, in = 84 °F and TWB, in = 72 "F

Outlet Condition: TDB,

out = 55 F and TDP out = 50 'F

Flow Rate: CFM of air = 3000

Standard Density of Air = 0.075 lbm/ft³

Specific Heat of Air = 0.24 BTU/lbm-'F.

The total cooling performed by the coil can be calculated using the following formula;

Sensible Cooling = CFM x Density x Specific Heat x (TDB, in - TDB, out)

Latent Cooling = CFM x Density x (HFG x (W, in - W, out)

Total Cooling = Sensible Cooling + Latent Cooling

First, we need to calculate the density of air at the inlet condition and outlet condition using the formula:

Density = 0.075 x (460 + TDB) / (460 + TWB)  at inlet and outlet condition

Density at inlet condition = 0.075 x (460 + 84) / (460 + 72)Density at inlet condition = 0.0666 lbm/ft³

Density at outlet condition = 0.075 x (460 + 55) / (460 + 50)Density at outlet condition = 0.068 lbm/ft³

The sensible cooling performed by the coil is;

Sensible Cooling = CFM x Density x Specific Heat x (TDB, in - TDB, out)

Sensible Cooling = 3000 x 0.0666 x 0.24 x (84 - 55)

Sensible Cooling = 1209.93 BTU/Hr

The total cooling performed by the coil is;

Total Cooling = Sensible Cooling + Latent Cooling

Here, Latent Cooling = CFM x Density x (HFG x (W, in - W, out))

At the inlet condition; W, in = (0.62198 x PWS) / (PB - PWS)W,

in = (0.62198 x 0.6237) / (14.433 - 0.6237)W,

in = 0.0427

At the outlet condition; W, out = (0.62198 x PWS) / (PB - PWS)W,

out = (0.62198 x 0.315) / (14.266 - 0.315)W,

out = 0.0237

HFG at average of inlet and outlet air temperature = 1074 BTU/lbm

Latent Cooling = CFM x Density x (HFG x (W, in - W, out))

Latent Cooling = 3000 x 0.0666 x (1074 x (0.0427 - 0.0237))

Latent Cooling = 27958.28 BTU/Hr

Therefore, Total Cooling = Sensible Cooling + Latent Cooling

Total Cooling = 1209.93 + 27958.28

Total Cooling = 29168.21 BTU/Hr

Therefore, the total cooling performed by the coil is 29168.21 BTU/Hr and the sensible cooling performed by the coil is 1209.93 BTU/Hr.

After the death of the Buddha, Buddhism became a formal religion through the efforts of his followers, who continued to spread his teachings and organized into communities known as sanghas. Over time, these sanghas developed a system of governance, with monastic councils, hierarchical structures, and formalized practices and rituals.

One key factor in the formalization of Buddhism was the development of the Tripitaka, a collection of the Buddha's teachings, which were written down in the Pali language and preserved by monastic communities. The Tripitaka contains three major sections: the Vinaya Pitaka, which outlines the rules and guidelines for monastic life; the Sutta Pitaka, which contains the Buddha's discourses on a wide range of topics; and the Abhidhamma Pitaka, which provides a detailed analysis of Buddhist psychology and philosophy.
The spread of Buddhism was also facilitated by the patronage of rulers such as Asoka, who supported the religion and helped to spread it throughout his empire. However, this support was not always consistent, and Buddhism faced periods of persecution and decline in various parts of the world. Despite these challenges, Buddhism has continued to evolve and adapt over the centuries, with different schools and traditions emerging in different regions. Today, Buddhism is practiced by millions of people around the world, and continues to offer a unique and powerful perspective on the nature of reality, the human condition, and the path to liberation.
