  9. First Law Of Thermodynamics


First law of thermodynamics state that internal energy is a function of state and the increase in internal energy is equal to the sum of the heat supplied to system and work done on system.

$\Delta U \, = \, Q + W$

$\Delta U$ is the increase in internal energy(U) of system,

Q is the heat supplied to the system,

W is the work done on the system.
