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 ]
