Passage / Comprehension

One mole of ideal monatomic gas follows the cycle ABC in the accompanying source graph of temperature against pressure. On AB, PT is constant. The universal gas constant is R.

Decrease in internal energy of gas in process CA is :-

Options:

Answer:

Solution:

$Δ U = n C_{V} dt$

$n = 1, C_{V} = \frac{3}{2} R$

$dt = (T_{A} - T_{C})$

$T_{A} = 300$

$T_{C} = 600$

$Δ U = - 450 R$
