Question

11. Charles's Law states that at constant pressure, the volume of a fixed amount of gas varies

directly with its temperature measured in degrees Kelvin. A gas has a volume of 250 ml at
300° K.
a Write an equation for the relationship between volume and temperature,
b What is the volume if the temperature increases to 420° K?

Answer 1

a.V=5/6T

b. 350 ml

Explanation:

a.

V∝T

or V=kT

where k is a constant.

V=250 ml

T=300° K

250=300 k

k=250/300=5/6

so V=5/6 T

b.

V=5/6 T

=5/6×420

=5×70

=350 ml
