The internal energy of a gas is given by U = 1.5 PV. It expands from 100 to 200 cm 3 against a constant pressure of 1.0×10 5 Pa. The heat absorbed (in J) by the gas in the process is

Taking the gas at the constant pressure throughout, Δ U = 1.5 PΔ V = 1.5×10 5 ×100×10 -6 = 15 J. w (by gas) = PΔ V = 10 J. q = Δ U + w = 25 J. Ans = 0025.

The internal energy of a gas is given by U = 1.5 PV. It expands from 100 to 200 cm³ against a constant pressure of 1.0×10⁵ Pa. The heat absorbed (in J) by the gas in the process is

Answer:

25.00

Solution:

Taking the gas at the constant pressure throughout, Δ U = 1.5 PΔ V = 1.5×10⁵×100×10^-6 = 15 J. w (by gas) = PΔ V = 10 J. q = Δ U + w = 25 J. Ans = 0025.
