Question

A copper block with a mass of 600 grams is cooled to 77K by being immersed in liquid nitrogen. The block is then placed in a Styrofoam cup containing some water that is initially at +50.0°C. Assume no heat is transferred to the cup or the surroundings. The specific heat of liquid water is 4186 J/(kg °C), of solid water is 2060 J/(kg °C), and of copper is 385 J/(kg °C). The latent heat of fusion of water is 3.35 x 105 J/kg.


I solved for maximum mass of of water and got 216.32 g but how do you find the minimum mass of water that could be in the cup?

Explanation / Answer

case1)i think for one case you took the final temperature as 0 celsius .( i think minium case) casse2)next to do the sum assuming some final temp T has reached
