Application of Specific Heat Capacity

Card 1: Car Radiator

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.
Card 2: Cooking utensils

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.
Card 3: Thermal Radiator

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.
Card 4: Phenomena of specific Heat capacity – Sea Breeze

Sea Breeze

  • Land has lower heat capacity than sea water. Therefore, in day time, the temperature of the land increases faster than the sea.
  • Hot air (lower density) above the land rises. Cooler air from the sea flows towards land and hence produces sea breeze.
Card 5: Phenomena of specific Heat capacity – Land Breeze

Land Breeze

  • Land has lower heat capacity than sea water. During night time, the temperature of the land drops faster than the sea.
  • Hot air (lower density) above the sea rises. Cooler air from the land blows towards sea and hence produces land breeze.
