Recall that a change in Celsius temperature is numerically equivalent to a change on the Kelvin scale. (b) The heat of fusion in this process is , F QLm = where 5 3.33 10 J/kg F L . Differentiating the expression with respect to t and equating the result with cond P , we have cond F dQ dm PL dt dt == . Thus, the rate of mass converted from liquid to ice is 5 cond 5 16.7 W (5.02 10 ) kg/s F P dm A A dt L × . (c) Since mV A h ρρ , differentiating both sides of the expression gives
