Question

to measure temperature of hot water during natural cooling and plot the graph of temperature versus time

Answer 1

Explanation:

The rate at which an object cools (i.e. how quickly its temperature decreases) depends upon several factors, including:

Surface area

Volume

Type of insulation

Temperature difference with the surroundings

For this investigation, the effect of the temperature of water upon the rate of cooling will be investigated. The temperature-drop over 5 minutes (600 seconds) will be measured for 200ml of water at different start temperature.
