Caluculate Change in internal energy when 5 moles of hydrogen is heate

1.	Caluculate Change in internal energy when 5 moles of hydrogen is heated to `20^(@)C` from , Specific heat of hydrogen at constant pressure is 8 cal `("mol"^(@)C)^(-1)`A. 200 calB. 350 calC. 300 calD. 450 cal
Answer» Correct Answer - C Given , `C_(p)=8 "cal"("mol"^(@)C)^(-1)` `C_(v)=C_(p)-R=8-2=6" cal "("mol"^(@)C)` `therefore"internal energy du"=mC_(v)(T_(2)-T_(1))=5xx6(20-10)` `300"cal" `
