Hii dear,


# Answer- 124 J


# Given-

dT=10°K

R=8.3J/mole°K

Qp=207J

n=1


# Formula-

For one mole of an ideal monoatomic gas

Cp-Cv=R


But heat at constant pressure is given by,

Qp=n×Cp×dT

207=1×Cp×10

Cp=20.7J


Also heat at constant volume is given by,

Qv=n×Cv×dT

Qv=1×(Cp-R)×dT

Qv=(20.7-8.3)10

Qv=12.4×10

Q=124J


Heat at constant volume to raise temperature by 10°K is 124J.
