Question

Will the volume of a gas increase, decrease, or remain unchanged for the following set of changes? The pressure is decreased from 6.33 atm to 1.05 atm, while the temperature is increased from 123°C to 234°C.

a) The volume will increase

b) The volume will decrease

c) The volume will not change

Answer 1

PV/T = P₀V₀/T₀

1.05*V/234=6.33*V₀/123

0.0045*V=0.0515*V₀

V/V₀=0.0515/0.0045

V/V₀=11.4.

So, the answer is a) the volume will increase
