40 G Of Argon Is Heated From 40c To 100c Physics Question

40 g of Argon is heated from 40⁰C to 100⁰C (R=2 cal/mole). Heat absorbed at constant volume is

Options

(a) 100 cal
(b) 80 cal
(c) 180 cal
(d) 120 cal

Correct Answer:

180 cal

Explanation:

Heat absorbed at constant volume = nCvdT
Now argon is monoatomic Cv = (3/2) R
Number of moles = 4/0/40 = 1
.·. Q = 1 × (3/2) × 2 × (100-40) = 3 × 60 = 180 cal.
