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 ,FQLm=where 53.33 10 J/kgFL=×.Differentiating the expression with respect to tand equating the result with condP, we have condFdQdmPLdtdt==.Thus, the rate of mass converted from liquid to ice is 5cond516.7 W(5.02 10) kg/sFPdmAAdtL−×.(c) Since mVAhρρ, differentiating both sides of the expression gives
