One mole of ideal gas expands freelt at ...

One mole of ideal gas expands freelt at 310 K from five litre volume to 10 litre volume. Then `Delta E` and `Delta H` of the process are respectively

A

0 and 5 cal

B

0 and `5xx300` cal

C

0 and 0

D

5 and 0 cal

Text Solution

Verified by Experts

The correct Answer is:
C
Free expansion `W=0`. Since Temperature is constant `DeltaU=0, DeltaH=0`
