A perfectly insulated container with no heat capacity is used to mix together the following two samples of water:

Water sample A.  16.1 grams of water at 14.2ºC

Water sample B.  20.3 grams of water at an unknown temperature.

After the two samples are combined, the final temperature of the combined solutions is 39.0ºC. What was the temperature of sample B before the samples were mixed together (Cs of water is 4.186 J/gºC)?

answer in degrees C with at least one decimal place.

    Ice at −15°C and steam at 120°C are brought together in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 50°C is present. Ignoring the container, find the ratio of the mass of steam to the mass of ice. The specific heat capacity of steam is 0.48 cal/(g·C°) and the specific heat capacity of ice is 0.5 cal/(g·C°).
