To cool her 0.200 kg cup of 75.0 C hot chocolate (mostly water), Heidi drops a 29,.97 g ice cube at 0 C into her insulated cup. After the ice cube melts, the temperature of the hot chocolate comes down to 54.8 C. a. How much energy was lost by the hot chocolate? The specific heat capacity of water is 1 cal/g C b. How much energy was gained by the ice cube just to melt to 0 C water?...

Brewed coffee is often too hot to drink right away. You can cool it with an ice cube, but this dilutes it. Or you can buy a device that will cool your coffee without dilution - a 250 g aluminum cylinder that you take from your freezer and place in a mug of hot coffee. If the cylinder is cooled to -20∘C , a typical freezer temperature, and then dropped into a large cup of coffee (essentially water, with a...

You cool a 120.0 g slug of red-hot iron (temperature 745 ∘C) by dropping it into an insulated cup of negligible mass containing 75.0 g of water at 20.0 ∘C. Assume no heat exchange with the surroundings. a) What is the final temperature of the water? T final = ? degrees C b) What is the final mass of the iron and the remaining water? m final = ? g

Your 200g cup of coffee is boiling hot (100 degrees celcius). You throw in 50g of -15 degrees celcius of ice to cool it off. Assuming negligible heat leaves the coffee-ice system during this process, what is the final temperature of your coffee? (The specific heat capacity of ice is 2.03 J/(g degree C and the specific heat capacity of water is 4.18 and the latent heat of melting for ice to water is 334J/g).
