Question

According to Charles’s Law, what happens to the volume of a gas when temperature decreases? Assume the gas is at constant pressure.

a.
It is constant
c.

It increases


b.
It decreases
d.

None of the above

Answer 1

Charle's law states that, v1 / t1 = v2 / t2 .
Hence,v(volume) is directly proportional to t(temperature).
Thus, the volume decreases.
