The amount of heat energy required to raise the temperature of 1 g of Helium

The Amount Of Heat Energy Required To Raise The Temperature Physics QuestionThe Amount Of Heat Energy Required To Raise The Temperature Physics Question

The amount of heat energy required to raise the temperature of 1g of Helium at NTP, from T₁K to T₂K is

Options

(a) (3/2) Nₐkв (T₂ – T₁)
(b) (3/4) Nₐkв (T₂ – T₁)
(c) (3/2) Nₐkв (T₂ / T₁)
(d) (3/8) Nₐkв (T₂ – T₁)

Correct Answer:

(3/8) Nₐkв (T₂ – T₁)

Explanation:

From first law of thermodynamics ∆Q = ∆U + ∆W
= (3/2) . (1/4) R (T₂ – T₁) + 0
= (3/8) Nₐkв (T₂ – T₁) [Since K = R / N ]
