Common Appliances Based On Heat
Common Appliances Based On Heat
Common Appliances Based On Heat: The various appliances that work on the principle of heat are:
Solar Cooker: It is a box made of insulating material such as wood, cardboard etc. The box has a glass cover to retain heat inside by greenhouse effect. The inside of the box is painted black to increase heat absorption.
Pressure Cooker: Pressure cooker increases the boiling point of water by increasing pressure. When the boiling point of water increases, food cooks faster. Pressure cookers are especially essential in hill stations because at higher altitudes the boiling point of water decreases due to lower atmospheric pressure.
Refrigerator and Air-conditioner: These are heat pumps, which transfer heat from inside to the external environment. These use a refrigerant, which is a compound that undergoes reversible phase change from gas to liquid. Common refrigerants include ammonia, sulphur dioxide, carbon dioxide and methane. The use of chlorofluorocarbons has been phased out due to concerns regarding depletion of ozone layer.
