For which of the following thermodynamic processes is the increase in the internal energy of an ideal gas is equal to the heat added to the gas

For which of the following thermodynamic processes is the increase in the internal energy of an ideal gas is equal to the heat added to the gas: At Constant volume.

According to the Ist Law of Thermodynamics

\dpi{100} \mathbf{\triangle Q = \triangle E + W}

W = pΔV

ΔQ = ΔE + pΔV

At constant volume ΔV = 0

ΔQ = ΔE + p(0)

ΔQ = ΔE

Hence, at constant volume, the internal energy of an ideal gas is equal to the heat added to the gas.
