Vedclass · Answer

(C) The process is isochoric because no work is done $(W = 0)$.For an isochoric process,the heat supplied is equal to the change in internal energy: $\Delta Q = \Delta U = n C_v \Delta T$.For a monoatomic gas,the molar heat capacity at constant volume is $C_v = \frac{3}{2}R$.Given: $n = 2\, mol$,$\Delta T = 373\, K - 273\, K = 100\, K$.Substituting the values:$\Delta Q = 2 	imes \frac{3R}{2} 	imes 100 = 300\,R$.

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