A 15kg iron (specific heat capacity is 450J/kg*0 C) heated to 1200 C is quenched

Question

A 15kg iron (specific heat capacity is 450J/kg*0 C) heated to 1200 C is quenched by dipping it into a water tank containing 50kg water (specific heat capacity is 4186J/kg*0 C) at 20 C. Suppose no heat is lost to the environment in this process, what will be the final temperature of the water after the quenching process? The same piece of iron at1200 C is quenched in a tank of 50kg oil initially at 20 C. The final temperature of the oil (and the iron) after the quenching is measured to be 48 C, what is the specific heat capacity of the oil?
