Column-1 represents the process
Column-2 represents the ΔU for that process and
Column-3 represents the work done expression for that process.

Which set correctly describes the process, when a pressure of 10 atm is applied on a gas container containing gas at 1 atm pressure at a constant temperature of 300K?
The given process is an irreversible isothermal compression.
Since, the process is isothermal
∴ΔU=0
So, from I law
ΔU=q+w
q=−w
or w=−q
