Vedclass · Answer

(D) The total heat required $(q)$ is the sum of the heat required to raise the temperature of the liquid $(q_1)$ and the heat required for phase change $(q_2)$.$q_1 = m 	imes c 	imes \Delta T$$q_1 = 1000 \, g 	imes 2.44 \, J \, g^{-1} \, K^{-1} 	imes (351.45 \, K - 293.45 \, K)$$q_1 = 1000 	imes 2.44 	imes 58 = 141520 \, J = 1.4152 	imes 10^5 \, J$$q_2 = m 	imes L_v$$q_2 = 1000 \, g 	imes 855 \, J \, g^{-1} = 855000 \, J = 8.55 	imes 10^5 \, J$$q = q_1 + q_2 = 1.4152 	imes 10^5 \, J + 8.55 	imes 10^5 \, J = 9.9652 	imes 10^5 \, J$Rounding to the nearest value,we get $9.97 	imes 10^5 \, J$.
