A fish swimming in water body when taken out from the water body is covered with a film of water of weight 36 g. When it is subjected to cooking at 100 $^\circ$ C, then the internal energy for vaporization in kJ mol $-$ 1 is $\underline{\hspace{2cm}}$. [nearest integer] [Assume steam to be an ideal gas. Given $\Delta$ vapH $^\Theta$ for water at 373 K and 1 bar is 41.1 kJ mol $-$ 1 ; R = 8.31 J K $-$ 1 mol $-$ 1]
