Phase change with q=mCsΔT!
Posted: Wed Jan 28, 2015 5:08 pm
Hi, this is actually regarding a specific problem in the textbook (7.39). We are trying to find the final temperature when you put an ice cube at 0°C into water at 45°C. The mass for the ice cube is 50.0 grams and for the water it is 400.0 grams. I understand we use the equation q=mCsΔT, but the part that I need help on is understanding why for the ice cube we use the specific heat capacity of water as a liquid and not as a solid?
