B. The pressure would be one-ninth of its original value.
C. The pressure would triple.
D. The pressure would remain the same.
According to Boyle's law, if the temperature were tripled as the number of moles and the volume were held constant, the pressure would triple (option C).
Boyle's law is the observation that the pressure of an ideal gas is inversely proportional to its volume at constant temperature.
However, when the temperature of a gas is increased, the pressure of the gas also increases provided the volume is constant.
According to this question, the temperature of a gas tripled as the number of moles and the volume were held constant.
Therefore, according to Boyle's law, if the temperature were tripled as the number of moles and the volume were held constant, the pressure would triple.

B. The birthrate may rise.
C. The death rate must fall.
D. The birthrate must fall.
If a population grows larger than the carrying capacity of the environment, the most likely to happen is:
A. The death rate may rise.
When a population grows larger than the carrying capacity of the environment, the resources available to the population will be depleted. This can lead to a decrease in the availability of food, water, and shelter. As a result, the death rate may rise.
The birthratemay also rise, but this is less likely. If the resources are already depleted, there may not be enough food and water to support a larger population. In addition, the stress of living in a crowded and resource-depleted environment may lead to an increase in stress-related deaths.
The other options, B. The birthrate may rise, C. The death rate must fall, and D. The birthrate must fall, are incorrect. The birthrate may rise, but it is not guaranteed. The death rate may fall, but it is not necessary. The most likely outcome is that the death rate will rise.
This is a concept known as carrying capacity, which is the maximum population size that an environment can sustain indefinitely. When a population exceeds the carrying capacity, the population will eventually crash. This can happen through a number of mechanisms, including starvation, disease, and conflict.

Answer:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
