K.C.S.E Physics Q & A - MODEL 2012PP1QN17
(a) Figure 11 shows how an underground room was ventilated. It had two vents, one at A and the other at B. A fire was lit at point C.
Explain what happened to the ventilation when the fire was lit.
(b) Explain how a vacuum flask minimizes loss of heat through radiation.
(c) In an experiment to investigate the unusual expansion of water, a fixed mass of water at O°C was heated until its temperature reached 20°C. On the axis provided, sketch a graph of density against temperature of the water from O °C to 20°C.
(d) An immersion heater rated 2.5 kW is immersed into a plastic jug containing 2 kg of water and switched on for 4 minutes. Determine;
