Question

At 0°C and 760 mm Hg pressure, a gas occupies a
volume of 100 cm3. Kelvin temperature of the gas is
increased by one-fifth and the pressure is increased one
and a half times. Calculate the final volume of the gas.

Answer 1

Given

T1 = 0°C=273k. T2=1/5*(273)+273=327.6k

P1= 760mm. P2=760+1/2*(760)=1140mm

V1= 100cc. V2=?

using ideal gas eqn.

P1*V1/T1=P2*V2/T2

760*100/273=1140*VE/327.6

On solving V2 will be equal to 80cc

hope it helps
