The change in internal energy when 5 mole of hydrogen is heated to `20^(@)C` from `10^(@)C`, specific heat of hydrogen at constant pressure is 8 cal/mol`.^(@)C` is

A

200 cal

B

350 cal

C

300 cal

D

475 cal

Text Solution

Verified by Experts

The correct Answer is:
C
`C_(V)=C_(p)-R=8-2=6cal//mol.^(@)C`
du=n`C_(V)(T_(2)T_(1))=5xx6xx10=300`
