Question

Flask containing air open to the atmosphere is heated from 300 kelvin to 500 kelvin then the percentage of a xscape to atmosphere is

Answer 1

Since pressure is constant, apply Charles law: V1/T1 = V2/T2 where V1=1L, T1=300K,T2=500K. ... An open vessel at 27°C is heated until three fourths mass of the air in it has been expelled. ... If the specific heat capacity (at constant pressure) of the gas is 21 J/mole K,
