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.
