Calculate the amount of work done when 2.0 liters of methane gas (CH₄) undergoes combustion in excess oxygen at 0 C and 1.0 bar. Assume the volume of water formed is negligible.

The work done by the gas from the calculation is 199 J.

Work done by a gas

The work done by a gas is a concept in thermodynamics and is often associated with changes in volume and pressure.

Understanding the work done by a gas is crucial in thermodynamics, as it is related to changes in internal energy and heat transfer, contributing to the understanding of processes like expansion, compression, and heat exchange in various systems.

We have to know that 1 bar = 0.98 atm

Work done = pdV

= 0.98 * 2 L

= 1.96 Latm

If 1 Latm = 101.325 J

1.96 Latm = 1.96 Latm * 101.325 J/ 1 Latm

= 199 J
