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 water:
A. 6 000 cal
B. 4 000 cal
C. 14,000 cal
D. 10,000 cal

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
