The temperature of 10 moles of a gas is ...

The temperature of 10 moles of a gas is increased from `30^(@)C` to `80^(@)C` at constant pressure. If R = 8.2 J/mole K, then the external work done in this process is

410 J

820 J

4100 J

2050 J

Text Solution

Verified by Experts

The correct Answer is:

`dw=Pdv=nRdT=10xx8.2xx50" "thereforedw=4100J`
