Kinetic Energy Review

Where would the water level be in each tube with the cold and hot wraps?

• Cold wrap: water level increased, closer to the stopper. Hot wrap: water level decreased, closer to the end of the tube.

• Cold wrap: water level decreased, closer to the end of the tube. Hot wrap: water level increased, closer to the stopper.

• Cold wrap: water level decreased, closer to the stopper. Hot wrap: water level increased, closer to the end of the tube.

• None of these.
