In this example, we will need to account for the latent heat associated with a phase change. A physics student wants to cool 0.25 kg of lemonade (mostly water) initially at 20°C by adding ice initially at -20°C. How much ice should she add so that the final temperature will be 0°C with all the ice melted? Assume that the specific heat of the paper container may be ignored.
Part A - Practice Problem: If the student had instead added 62 g of ice initially at -25°C to her lemonade, how much of the ice would be left after the mixture had cooled to 0°C? Express your answer with the appropriate units. HA ? Am 32 g Submit Previous Answers Request Answer X Incorrect; Try Again
