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

What is the stall speed at sea level of an airplane that weights 10000 lbs., has a wing area of 300ft^2, and a maximum lift coefficient of 1.4? what is the stall speed if flaps that double cl,max are applied?

If a balloon is taken outside on a very cold day, what will occur?

Fill in the blanks with the numbers is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
