Vedclass · Answer

(B) The energy supplied is $Q_{	ext{supplied}} = 0.93 \, W \cdot h = 0.93 	imes 3600 \, J = 3348 \, J.$The energy required to melt $10 \, g$ of ice at $0 \, ^\circ C$ is given by $Q_{	ext{req}} = m \cdot L_f,$where $L_f = 80 \, cal/g = 335.2 \, J/g$ (using $1 \, cal = 4.19 \, J$).Thus,$Q_{	ext{req}} = 10 \, g 	imes 335.2 \, J/g = 3352 \, J.$Comparing the values,$Q_{	ext{supplied}} \approx Q_{	ext{req}} \approx 3350 \, J.$Since the supplied energy is almost exactly equal to the latent heat required for phase change,the entire block of ice just melts.

When $0.93 \, W \cdot h$ of energy is supplied to a block of ice weighing $10 \, g,$ it is found that
