Two moles of ideal helium gas are in a rubber balloon at `30^@C.` The balloon is fully expandable and can be assumed to require no energy in its expansion. The temperature of the gas in the balloon is slowly changed to `35^@C.` The amount of heat required in raising the temperature is nearly (take R
`=8.31 J//mol.K`)

Text Solution

Verified by Experts

The correct Answer is:
d
`DeltaQ=nC_(p)DeltaT`
`=2((f)/(2)R+R)DeltaT`
`2=[(3)/(2)R+R]xx5`
`=2xx(5)/(2)xx8.31xx5=208J`
