NEET levelSingle correct optionDifficulty 1 of 3td173

Taking $R = 8.314 J mo l^{- 1} K^{- 1}$ , the heat needed to raise the temperature of $1 mol$ of a monatomic ideal gas by $10 K$ at constant volume is nearest to

A $207.8 J$
B $83.1 J$
C $124.7 J$
D $291.0 J$

Answer: C

At constant volume

q_{V} = n C_{V} Δ T = 1 \times 1.5 \times 8.314 \times 10 = 124.7 J
