A hot air balloon has an air vent that keeps the air pressure inside and outside the same. Allen observes that a hot air balloon rises up when the gas molecules inside it are

heated. Which of the following laws is used to understand the behavior of the gas and why?

The high temperature brings the gas molecules closer together according to Charles's law because this law describes how a gas will behave at constant pressure.

The high temperature makes the gas molecules spread apart according to Charles's law because this law describes how a gas will behave at constant pressure.

The high temperature lowers volume according to Boyle's law because this law describes how a gas will behave when the number of moles remains constant.

The high temperature raises volume according to Boyle's law because this law describes how a gas will behave when the number

moles remains constant.

The high temperature makes the gas molecules spread apart according to Charles's law because this law describes how a gas will behave at constant pressure.

Explanation:

Charles' law seeks to explain the relationship between the volume and temperature of a gas at constant pressure.

It states that at constant pressure, the volume of a gas is directly proportional to its temperature. The term directly proportional means that whatever happens to the temperature will happen to the volume

Hence, when we have a temperature rise, there will be a corresponding increase in volume and when there is a temperature drop there will be a decrease in volume.

Thus, it is not out of place for Allen to

observe that when there is a rise up in the volume of the hot air ballon, it is expected that there is a temperature rise
