Question

A sample of nitrogen gas is inside a sealed container. The container is slowly compressed, while the temperature is kept constant. This is a(n) ________ process.

a. constant-volume
b. isothermal
c. adiabatic
d. isobaric

Answer 1

b. isothermal

Step-by-step explanation:

When a thermodynamic process occurs and the temperature remains constant, it is said to be an isothermal process.

The prefix "iso" means "equal", so the word isothermal indicates that the temperature remains equal in the process, and that is what happens in the situation described, the volume is varied (compressed) while maintaining the sample of nitrogen gas remains at a constant temperature.
