Under the isothermal condition, a gas at 300 K expands from 0.1 L to 0.25 L against a constant external pressure of 2 bar. The work done by the gas is (Given that 1 L bar = 100 J )

Question

Under the isothermal condition, a gas at 300 K expands from 0.1 L to 0.25 L against a constant external pressure of 2 bar. The work done by the gas is (Given that 1 L bar = 100 J ), - 30 J, 5 k J, 25 J, 30 J

MARKS App · Accepted Answer

The work done by a gas, W = P external × ΔV = - 2 × v 2 - v 1 = - 2 × 0.25 - 0.10 = - 0.30 L bar Given, 1 L bar = 100 J . So, W = - 0 .3 × 100 = - 30 J .
