The entire block just melts

Vedclass · Answer

(C) Energy supplied $E = 0.93 \, Wh = 0.93 	imes 3600 \, J = 3348 \, J$.Heat required to melt $10 \, g$ of ice at $0^{\circ}C$ is given by $Q = mL_f$,where $L_f = 80 \, cal/g = 80 	imes 4.184 \, J/g = 334.72 \, J/g$.$Q = 10 \, g 	imes 334.72 \, J/g = 3347.2 \, J$.Since the energy supplied $(3348 \, J)$ is approximately equal to the heat required to melt the ice $(3347.2 \, J)$,the entire block of ice just melts.

$0.93 \, Wh$ of energy is supplied to a block of ice weighing $10 \, g$. It is found that:
