Question

when one mole of gas is heated at constant volume temperature is raised from 298to308 heat supplied to gas is 500J then which statement is correct

Answer 1

The statement of 1st is correct because the volume is increase

Answer 2

Answer:

Explanation:

As we know that  

ΔH=ΔE+PΔV

               When  

ΔV=0

                     

∴

ΔH=ΔE

               From first law of thermodynamics                  

ΔE=q−W

               In given problem  

ΔH=500J

               

−W=−pΔV,

                         

ΔV=0

               So,          

ΔE=q=500J
