A group of pupils carried out an experiment with four different liquids.
They wrapped paper tissues around the bulbs of four thermometers. They secured the tissues with rubber bands. Each thermometer was then dipped into a different liquid and removed. The temperature was recorded. The reading on each thermometer was then noted every two minutes.
The pupils carried out the experiment with propanone again. However, this time they did not wrap the thermometer in paper tissue but just dipped the glass bulb into the propanone and removed it. Suggest how their second set of results would be different.
