Shoto, from My Hero Academia, has a power (or a “quirk”) that allows him to make large amounts of ice from nothing. Let us say that due to a fire a 361 kg steel beam is heated to 943.˚C and Shoto creates 390. kg of ice at 0.00˚C around it to cool it down.  What is the final temperature of the system after the ice melts and it reaches thermal equilibrium? The specific heat of steel is 502 J/kg˚C.  The specific heat of water is 4186 J/kg˚C.  The latent heat of fusion for ice is  3.33⋅10^5 J/kg.

23.4 g of coffee beans at room temperature (18.6 °C) is mixed into 316 g of water at 96.8 °C in an effort to make coffee. The entire system is poured in a 363 g ceramic mug. Assume the mug is initally also at room temperature (18.6 °C). What is the final temperature of the mixture? The specific heat of ground coffee beans is 1670 J/kg˚C, the specific heat of water is 4186 J/kg˚C, and the specific heat of the mug is 850. J/kg˚C.
