Question

One mole of an ideal gas is confined to a container with a movable piston. The questions below refer to the processes shown on the PV diagram at right. Process I is a change from state X to state Y at constant pressure. Process II is a change from state W to state Z at a different constant pressure.

Kind of looks like this:

l__________________________V

1) Is the temperature of state X greater than, less than, orequal to the temperature of state Y? Please explain.

2) Is the temperature of state W greater than, less than, orequal to the temperature of state Z? Please explain.

Explanation / Answer

1 . x and y are at the same Pressure => As volume increases, temperature increases => y is at a greater temperature than x 2. w and z are at the same Pressure =>As volume decreases, temperature decreases => z is at a greater temperature than w
