An ideal gas is filled in a closed rigid and thermally insulated container. A coil of `100Omega` resistor carrying current 1 A for 5 minutes supplies heat to the gas. The change in internal energy of the gas is

A

`10 kJ`

B

`20 kJ`

C

`30 kJ`

D

`0 kJ`

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaU = Q = I^(2) RT = 1^(2) xx 100 xx5 xx 60J`
` =30 KJ (DeltaW = 0)`
