Insulation

Keeping things warm

Aim: To find out which of these four materials is a better nonconductor to weewee under the akin conditions for 5mins the materials are ripple enlace, aluminum foil, Cotton wool and Tissue paper.

Prediction: I predict that Bubble wrap or like wool give be the best insulators due to the fact that they are thicker materials. Bubble wrap also has thick holes, which will trap the incite, but like wool is the thickest material so I think that cotton wool will be the best insulator.

Plan: For this experiment I will need to get all my required equipment. I will hold back too had the same marrow of water at the same starting temperature. The same length of for each one material and the tin must be covered same length down with each material otherwise it routine be a fair shew, the test should also go on for the same amount of time. For carrying out this experiment we will also be required to consider all the refuge issues such as wearing goggles too father sure that no harmful chemicals can get into our eyes.

Fair test: A fair test is when the whole test is carryed equally.



In our test we had to make sure that we used the same amount of water and the same temp of water we had to also have the same length of material and it had to cover the same largeness of the tin.

Convection:

Convection is the flow of heat a hot region to a cool region, as opposed to the microscopic transfer of heat between atoms involved with conduction. Suppose we consider heating up a local region of air. As this air heats, the molecules bed covering out, causing this region to become less dense than the surrounding, unwarmed air. For reasons...
