Physics 9-1 0972: Thermal Physics Topical Past Paper Questions

A student is investigating electrical heaters that are used in the school laboratory to heat beakers of water. The heaters are all 12V heaters with the same power rating. The student thinks that some heaters are more efficient than other heaters. Plan an experiment to compare how…

A student investigates the cooling of water in a metal container. (a) The student uses a thermometer to measure room temperature $ \theta_{R} $. Room temperature is $ 23^{\circ}C $. Show clearly, on Fig. 2.1, the reading $ \theta_{R} $. Fig. 2.1 [1] (b) Fig. 2.2 shows the apparat…

A student investigates the time taken for water to evaporate to dryness when heated from above. Fig. 4.1 shows the set-up. The power of the heater is constant. The following is also available: supply of water at room temperature • metre ruler. Fig. 4.1 Plan an experiment to inves…
