Question

What is specific heat capacity and it's application in daily life

Answer 1

Explanation:

Specific heat gives the amount of heatenergy required for heating a substance of 1 unit mass by 1 °C. So more the specific heat, more the energy required for heating the substance. 1) Utensils used for making tea or coffee, or cooking vegetables or rice are made of materials of low specific heat.

Answer 2

Answer:

Physics > Thermal Properties of Matter > Specific Heat Capacity

Specific Heat Capacity

"The heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree) is called specific heat capacity".

When you are out on the beach, have you noticed that the water is cold whereas the sand is hot! The sun is the same there, then why this difference in the temperature? You must have given it a thought! The temperature of a solid and liquid element rises when we supply heat to it. If we supplied the same amount of heat to two different kinds of solid then rise in temperature may be different in both the solids. So, depending upon the nature of the solid, the rise in temperature varies for different kind of solids. This phenomenon is known as Specific heat Capacity.

Explanation:

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.
