Application of Specific Heat Capacity
Car radiator
- Water is pumped through the channels in the engine block to absorb heat.
- Water is used as the cooling agent due to its high specific heat capacity.
- The hot water flows to the radiator and is cooled by the air flows through the fins of the radiator.
- The cool water flows back to the engine again to capture more heat and this cycle is repeated continuously.
Cooking utensils
- Cooking utensils are made of metal which has low specific heat capacity so that it need less heat to raise up the temperature.
- Handles of cooking utensils are made of substances with high specific heat capacities so that its temperature won’t become too high even if it absorbs large amount of heat.
Thermal Radiator
- Thermal radiators are always used in cold country to warm the house.
- Hot water is made to flow through a radiator. The heat given out from the radiator is then warm the air of the house.
- The cold water is then flows back to the water tank. This process is repeated continuously.
- Water is used in the radiator because it has high specific heat capacity.
