Vedclass · Answer

(C) When no work is done,the process is isochoric (constant volume).For an ideal monatomic gas,the molar heat capacity at constant volume is $C_V = \frac{3}{2} R$.The amount of heat required is given by the formula $\Delta Q = n C_V \Delta T$.Given: $n = 2 \, mol$,$\Delta T = 373 \, K - 273 \, K = 100 \, K$.Substituting the values:$\Delta Q = 2 	imes \left( \frac{3}{2} R ight) 	imes 100$$\Delta Q = 3 	imes 100 	imes R = 300 \, R$.

If $R$ is the universal gas constant,the amount of heat needed to raise the temperature of $2 \, mol$ of an ideal monatomic gas from $273 \, K$ to $373 \, K$ when no work is done is: (in $, R$)
