Give the mathematical expression for the first law of thermodynamics.
(N/A) The mathematical expression for the first law of thermodynamics is given by: $\Delta U = q + w$
where $\Delta U$ is the change in internal energy,$q$ is the heat supplied to the system,and $w$ is the work done on the system.
