b. The system releases 75 J of heat, and its volume is halved.
c. The system absorbs 75 J of heat, and its volume is halved.
d. The system absorbs 75 J of heat, and its volume doubles.

Answer:

c. The system absorbs 75 J of heat, and its volume is halved.

Explanation:

Adding heat raises the temperature of the gas, which increases the speed of the molecules.

Halving the volume forces the molecules closer together, which increases the number of collisions between the molecules.
