Question

A balloon contains 3.1 liters of nitrogen gas at a temperature of 80 k and a pressure of 101 kpa. part a if the temperature of the gas is allowed to increase to 22 ∘c and the pressure remains constant, what volume will the gas occupy?

Answer 1

since temperature is constant we use Charles law which relate temperature and volume
therefore From Charles law equation that is T1/v1=T2/V2
T1=80k
V1=3.1L
T2=22+273=295k
V2=?

80k/3.1L=295k/V2
by cross multiplication
V2=(3.1L x295k)/80k=11.43L
