Investigating the effectiveness of different materials as thermal insulators

Question 1

How do you carry out the experiment

Answer 1

1. Boil water in a kettle and pour water into a sealed container(beaker and lid)
2. Measure the initial mass of the water and record the starting temperature of the water
3. Seal the container and leave it for 5 minutes. Measure the time on a stopwatch.
4. Remove the lid and measure the final temperature of the water
5. Repeat the experiment but each time, wrap a different material around the container once sealed, making sure that the mass is the same mass as the first try and the temperature is the same

Question 2

What should the experiment tell you?

Answer 2

That the temperature difference is reduced when a thermal insulating material is used
