Question

An ideal gas expands into a vacuum in a rigid CONTAINER. As a result we have a:

a. Decrease in internal energy

b.Increase in pressure

c. Change in entropy

d. Change in temperature

Answer 1

Answer #1

c. Change in entropy

Note- expansion of ideal gas into vacuum increases entropy while internal energy remains constant so does temperature. And pressure decreases.

Answer 2
