The heat of fusion for water is the amount of energy required to water when added

Atank contains 240 liters of fluid in which 10 grams of salt is dissolved. brine containing 1 gram of salt per liter is then pumped into the tank at a rate of 6 l/min; the well-mixed solution is pumped out at the same rate. find the number a(t) of grams of salt in the tank at time t.

Why doesn't heat added to water make the tempature rise above 100c

Consider this initial-rate data at a certain temperature for the reaction described by
