A) 30 cal
B) 50 cal
C) 60 cal
D) 80 cal
Correct Answer: B
Solution :
Heat at constant pressure \[{{Q}_{p}}=m{{C}_{p}}\Delta \theta \] Heat at constant volume \[{{Q}_{V}}=m{{C}_{V}}\Delta \theta \] \[{{Q}_{p}}={{Q}_{V}}=M({{C}_{p}}-{{C}_{V}})\Delta \theta \] \[70-{{Q}_{V}}=mR\Delta \theta \]You need to login to perform this action.
