1. A group of pupils carried out an investigation using the apparatus as shown

below. They prepared three glasses with the same amount of hot water .Each

glass is wrapped with cotton wool , coconut husk and plastic sheet respectively.

The thermometer is inserted into each glass and the thermometer reading is

recorded after 30 minutes

Table below shows the results of the experiment
