For an isochoric process, what is the expression of the First Law of Thermodynamics?
Formula: Q V = Δ U = n C(V,m) Δ T. Explanation: In a constant volume process ( Δ V = 0 ), no work is done by/on the system via volume change ( W = 0 ). The hea…

Formula and explanation
Formula: Q V = Δ U = n C(V,m) Δ T. Explanation: In a constant volume process ( Δ V = 0 ), no work is done by/on the system via volume change ( W = 0 ). The heat absorbed by the system Q V is entirely used to increase its internal energy Δ U. Applicability: Isochoric process of an ideal gas.
