CSEC Physics · January 2012 · Paper 2 · Question 5(b)(i)

Figure 6 shows a sketch of a natural convection solar water heating system.

The energy absorbed by the solar collector is 300 kJ and 40% of this is transferred to the 2 kg of water in the copper tubing. If the initial temperature of the water is 27 °C, calculate the final temperature of the water.
