Q

Background information:

A

Insulating a hot object reduces the rate of heat loss to the surroundings. In this practical lesson, you will insulate a container using an insulating material and record the temperature over time. You will then vary the number of insulation layers to determine the relationship between insulation thickness and energy transfer
