The specific heat of a gas constant volu...

The specific heat of a gas constant volume is 20 J/mol K. when two moles of such gas is heated through `10^(@)C` at constant pressure, what is the increase in thernal energy and work done? (R=8 J/mol K)

200J, 160 J

400 J, 260 J

400 J, 160 J

200 J, 460 J

Text Solution

Verified by Experts

The correct Answer is:

`du=nC_(V)dT`
`=2xx20xx10=400`J
`domega=nRdT`
`=2xx8xx10=160J`
