Question

A. Which of the four thermal processes describes the pressure-volume relationship at a constant temperature?

Answer 1

Answer:

Boyle's law, which describes the relationship between the pressure and the volume of a gas when the temperature remains constant.

Explanation:

Boyle's law says that the pressure of a gas in a closed container is inversely proportional to the volume of the container that contains it, when the temperature is constant. This means that if the pressure increases, the volume decreases, and if the pressure decreases, the volume increases.

The formula that describes this law is as follows:

P1 * V1 = P2 * V2

Where P1 is the gas pressure in the initial state, V1 is the volume of the gas in the initial state and P2 and V2 is the pressure and volume in the final state.

Answer 2

Boyles law describes pressure volume relationship at constant temperature  pressure is directly proportional  to volume at constant tamparature
