In pairs, do this experiment to observe and understand heat dissipation from water in a closed system.
2 Fill a beaker with hot water.
3 Place the lid on the beaker to prevent evaporation.
4 Measure and record the initial temperature of the water as soon as it is poured into the beaker.
5 Remove the lid briefly to measure and record the temperature of the water once every 5 minutes for half an hour.
