Question 46

An investigation was carried out to compare how well different materials insulate a container of hot water, modelling thermal regulation and heat loss. One beaker was wrapped in a layer of bubble wrap, and another beaker was wrapped in a layer of cotton wool.

Diagram showing two experimental setups on heatproof mats. Setup A shows a beaker wrapped in bubble wrap with a lid and a thermometer inserted through it. Setup B shows an identical beaker wrapped in cotton wool, also with a lid and thermometer. Both beakers are filled with hot water.

Describe a control that could be used for this investigation.
