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.

    Heat will also escape by radiation. This is the transfer of energy by electromagnetic waves. Energy will leave the cup and spread out around it meaning the fluid will have less thermal energy. If insulation is put round the cup this will reduce heat loss. Because the cup and the insulation will be non-metal, the energy will be transferred through them by hot particles vibrating.

    The water particles at the top of the can will radiate the heat energy into the surrounding air. For heat to radiate it does not need to be in contact with matter. Heat can radiate for some thing to another body through a complete vacuum, this is how the sun heats up the earth.
