Application of thermal energy transfer
making use of thermal energy knowledge.

application of conduction

comparing the singe glazing and double glazing.

to prevent this,man has designed roof space

even,ventillators.

common appications:
cooking utencils -kettles,pots,pans are usually made of aluminum or stainless steel.since metal is a good conductor,which takes less time to heat up to high temperature

thermometers-the tip of the thermometer is made of metal,since metal conducts heat readily to give accurate readings

handles of heating equipment-are usually made of insulators,such as plastic.this is in order to prevent handling it without scorching our hands

wollen clothes- since wool is an insulator,it keeps us warm in winter

applications of convection:



common applications :electric kettle,water heaters,air conditioners,refrigerator.

air conditioners are usually placed at the top of the room since hot air rises,the air conditioners cools it.

application of radiation:

greenhouses-help plants grow better in cold climates.by day, the suns infrared passes through the roof of the green house,warming the contents of the greenhouse.the infrared emitted by the contents however are unable to penetrate out of the greenhouse.thus the trapped heat is trapped in the greenhouse,over time,the trap infrared builds up and the temperature rises

roofs- a thin foil of shiny metal is laid out,since shiny surfaces are bad absorbers and emitters,the house is able to maintain a regular comfortable temperature.
