A student performs an experiment where he uses a heating coil to heat the water as shown in the figure. The initial temperature of the water is measured as $10^{\circ} C$. After switching it ON for 5 min, the student records the temperature of the water as $18^{\circ} C$.
The water is allowed to return back to its initial temperature. The activity is then repeated with another heating coil having half the length of the original heating coil. He notices that after 5 min, the temperature of the water reads $14^{\circ} C$. Which statement can be concluded based on the activity?
(a) Reading on thermometer reduces with time.
(b) Temperature of water drops with every repetition.
(c) Length of the material affects the amount of heating.
(d) Temperature of the water increases after a certain period of time.
