Question

find kinetic energy of 5 litres of a gas at S.T.P​

Answer 1

Answer:

The kinetic energy of gas molecule is given by 3/2kT

Given: V=8lts=8;P=5atm

From the ideal gas equation: PV=nRT

nT=PV/R=8×5/0.082

Total kinetic energy =N×3/2kT where N is the total gas molecules

=(40/0.082)×6.02×10

23

×1.38×10

−23

×3/2

=6078 joules
