Question

Mathematical equation of first law of thermodynamics for isochoric process is ______.

विकल्प

• ΔU = q_v

• ΔU = q_y

• q = - W

• ΔU = W

Answer 1

Mathematical equation of first law of thermodynamics for isochoric process is ΔU = q_v.

Explanation:

For an isochoric process, ΔV= 0

In this process, Ace to the first law of thermodynamics

q = ΔU - W

q = ΔU - pΔV

As ΔV = 0

q_v = ΔU
