Physics FIRST LAW OF THERMODYNAMICS

First Law of Thermodynamics

It is the consequence of conservation of energy for gaseous system.

`text(Heat supplied to the gas = Increase in internal energy + work done by the gas)`

`Q=DeltaU + W`

Q = +ve `=>` Heat is supplied to the gas
Q = -ve `=>` Heat is taken out from the gas

In differential form `dQ=dU+dW`

And `dQ = nCdT`

`C =` Molar specific heat
