Roof Heat Proofing Chemical Roof Heat Proofing Karachi. Heat is a form of energy which can transferred through radiation. You might have experienced that from sitting around a bonfire. Although you are not touching the fire, you can feel it radiating heat in your face even if it is cold outside. If you like to drink your tea hot, you might ask how heat transfer can be reduced, and how the tea keeps from cooling down? Roof Heat Proofing Chemical Roof Heat Proofing. The answer is thermal insulation. Insulation means creating a barrier between the hot and the cold object that reduces heat transfer by either reflecting thermal radiation or decreasing thermal conduction and convection from one object to the other.

Barriers that conduct heat very poorly are good thermal insulators, whereas materials that conduct heat very well have a low insulating capability. Roof Heat Proofing Chemical Roof Heat Proofing In this activity, you will test which materials make good or bad thermal insulators with the help of a glass of hot water. Which material do you think will be most effective.

Although the fridge temperature is very low, your hot water has a high temperature. As heat energy flows from the hot object to the cold object, the heat energy from your hot water will be transferred to the surrounding cold air inside the fridge once you put the glass jars inside.
