Joule's Law

Joule's Law:

It states that, the change of Internal Energy (ΔE) of a perfect gas is directly proportional to Change in temperature (ΔT)

Mathematically:

ΔE ∝ ΔT

ΔE = mC(ΔT)

ΔE = mC(T₂-T₁)

m= mass of gas

c = Specific Heat

An important consequence of this law is that, if the Temperature (T) of a given mass of gas changes from T₁ to T₂ , then Internal energy(E) will change from E₁ to E_2, irrespective from changes in pressure(p) and volume(v) of the gas.
