One mole of an ideal monatomic gas requires 210 J heat to raise the temperature by 10 K , when heated at constant temperature. If the same gas is heated at constant volume to raise the temperature by 10 K then heat required is

A

238 J

B

126 J

C

210 J

D

350 J

Text Solution

Verified by Experts

(b) `(DeltaQ)_(P)=muC_(P)DeltaT and (DeltaQ)_(V)=muC_(V)DeltaT`implies `((DeltaQ)_(V))/((DeltaQ)_(P))=(C_(V))/(C_(P))=((3)/(2)R)/((5)/(2)R)=(3)/(5)" " [ :.(C_(V))_(mono)=(3)/(2)R,(C_(P))_(mono)=(5)/(2)R]`
`=(DeltaQ)_(V)=(3)/(5)xx(DeltaQ)_(P)=(3)/(5)xx210=126J`
