An investigation has been completed, similar to the one on latent heat of fusion, where steam is bubbled through a container of water. steam condenses and the lost energy heats the water and container. given the following data, do the calculations requested.

mass of the aluminum container 50 g
mass of the container and water 250 g
mass of the water 200 g
initial temperature of the container and water 20°c
temperature of the steam 100°c
final temperature of the container, water, and condensed steam 50°c
mass of the container, water, and condensed steam 261 g
mass of the steam 11 g
specific heat of aluminum 0.22 cal/g°c

heat energy gained by the container heat =
770 cal
550 cal
330 cal
220 cal

heat energy gained by the water

14,000 cal
10,000 cal
6000 cal
4000 cal

what is the latent heat of vaporization for water?

latent heat =

79.7 kcal/kg
5900 kcal/kg
540 kcal/kg

does the amount of heat energy lost by the steam equal that gained by the aluminum and water?

yes
no

total heat lost by the steam as it condenses and reaches 50°c.

heat =

given the data above, determine the total heat energy gained by the container and water.

2900 cal
6300 cal
6500 cal
7800 cal

latent heat lost by the steam as it condenses to water at 100°c.

heat =

550 cal
6500 cal
5900 cal
