Question

What happens to a gas when the temperature decreases?

a.It expands.

b.It rises.

c.It condenses.

d.It becomes less dense.​

Answer 1

Answer:

d. it becomes less dense.

Explanation:

on decreasing the temperature the kinetic energy of molecules decreases and the volume increases so the density decreases or they become less dense and on further decreasing the temperature it condenses to liquid form.

Answer 2

Answer:

c. It condenses

Explanation:

Because when the temperature decreases the molecules of gas slow down and they attract each other then gas convert in liquid.
