The latent heat of fusion of water is 334 j/g or 80 cal/g at 0 degrees celsius. a. what is the heat in joules required to melt 25 grams of ice? b. what is the heat in calories? (1 kcal=4184 j) c. what assumption did you make about the temperature?

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
