A student constructs a device for absorbing thermal energy from the Sun. The student places the white plastic pipe in sunlight. The cold water flows slowly from Tank A to Tank B. Energy from the Sun heats the water in the pipe.
Determine the rise in temperature of the water as it passes between Tank A and Tank B.
Determine Work it out from what you are given or from the figure, and show how you got there.

A student constructs a device for absorbing thermal energy from the Sun: cold water flows slowly from Tank A through a long white plastic pipe placed in sunlight into Tank B, and energy from the Sun heats the water in the pipe.
The student wants to increase the thermal energy absorbed by the water in the pipe. State three improvements she can make to increase the thermal energy absorbed.
State A short answer. No explanation is needed, and adding one cannot earn extra marks.
