Investigation To See How Conduction Affects Heat Transfer

Extracts from this document...

Introduction

Investigation To See How Conduction Affects Heat Transfer Safety How will you make sure your investigation is safe? What potential dangers are there? * Hot water * The copper calorimeter - the calorimeter will become very hot when it is filled with he hot water. Use protection when transporting the calorimeter. * The kettle - don't mix water with electricity. Fair Test How will the investigation be kept fair? What variables will be constant? How will you make sure they are kept constant? * The amount of water in the copper calorimeter - mark the calorimeter instead of measuring, as the water will transfer heat when it is being measured. * Cool the calorimeter down before using the next layer of insulation. ...read more.

Over what length of time? The results I will be taking will be a measure of how much heat the calorimeter is losing. I intend on taking three sets of results for each layer and then taking the average. I will take a time reading every minute for 13 minutes. Prediction Linking to Theory I predict that with one layer, the heat will be transferred faster than with two or three layers. The time taken to heat will increase with every layer added. This is because the layers act as insulation and the carpet has air pockets within it. Air is a good insulator and the more jackets added, the higher the amount of trapped air, and so the heat won't be transferred from the calorimeter as quickly. ...read more.

    This is because the trapped air inside the 'bubbles' stops convection currents and is a very good insulator. * Equipment I will use equipment that is suitable to make the most accurate measurements and that will give me the best results.

    This process can also be called the Wave Motion. Evaporation This could cool down the water, as when the water evaporates it will take the heat away with it in the same way evaporating sweat cools down our bodies. If I use a lid this could slow down this process.

  2. What affects the rate of heat transfer through an Aluminium can?

    > Radiation- this is the transfer of heat from a hot object in the form of waves. Heat radiation can also be called infrared radiation, and it consists purely of electromagnetic waves of a certain frequency. It's just below visible light in the electromagnetic spectrum.
