Calculate the amount of work done when 1 mole of a gas expands from a volume of 1 litre to a volume of 5 litres against the constant external pressure of 1 atmosphere (1 litre atmosphere =101.3J)

Thermodynamic process differ based on the manner in which it is carried out. a) Distinguish between reversible and irreversible processes. b) Calculate the amount of work done when 2 moles of a gas expands from a volume of 2 L to 6 L isothermally and irreversibly against a constant external pressure of 1 atm.

A gas expands from 1l to 6l against a constant pressure of 1 atm and it absorbs 500J of heat Delta U is
