A) \[\frac{3}{2}RT\]
B) \[\frac{3}{2}kT\]
C) \[\frac{1}{2}RT\]
D) \[\frac{1}{2}kT\]
Correct Answer: C
Solution :
The total of all the possible kinds of energy of a system is called its internal energy. Internal energy, \[\Delta U={{C}_{v}}NkT\] \[={{C}_{v}}nRT[\because n=1]\] \[=\frac{3}{2}RT{{[\because {{C}_{V}}=\frac{3}{2}for\text{ }monoatomic\text{ }gas]}^{2}}\] 3 translation degree of freedom.
