What is Specific Heat? Definition of specific heat, complete information about use in daily life

Specific Heat in hindi- Hello friends, in our previous article, we talked about specific heat. Today in this article we will look at the definition of specific heat, definition of specific heat, specific heat of water and many more aspects. And try to understand better what is specific heat.

Specific Heat in Hindi-

Definition of specific heatThe amount of heat required to raise the temperature of a unit mass of a substance by 1°C is called the specific heat of that substance. ,

• It is denoted by S. Its unit is calorie per gram/°C or joule/kg/°C.
•Q=sm×dt, s=constant, Q=heat, m=mass, dt=increase in temperature.

Basically now you must have understood this specific heat What happens, now we will try to find out where are the examples of specific heat in our real life.

Explanation of Specific Heat

Specific heat –If one gram of water, one gram of kerosene oil and one gram of copper at room temperature (25°C) are given one calorie each, then the temperature of water is 25°C, the temperature of kerosene is 27°C and copper The temperature becomes 35°C. Therefore, it shows that if the same amount of heat is given to the substances of the same mass at the same temperature, then the rise in temperature of each is different.

In other words, “If different substances of the same mass are taken, which have the same initial temperature, then different amounts of heat are required to be heated to a certain temperature. If by taking the mass of one gram part of a substance, its temperature is increased by one degree centigrade, then the heat given in this process is specific heat is called.”

The specific heat of different substances, that is, the heat required to raise the temperature of one gram of substance by one degree centigrade, is shown in the following table.

matter Specific heat
Water 1.0
iron 0.11
Aluminum 0.21
magnesium 0.25
lead 0.03
Carbon 0.17
zinc 0.092
marble 0.21
Ice 0.50

Specific heat of water –

The specific heat of water is higher than that of all liquids and solids, that is, if the temperature of different substances of equal weight is increased equally, then water will require the most heat and if cooled to the same temperature, then water will require the most. The amount of heat that will be received.

This is the reason that hot water is passed through the pipes to heat the room in autumn. Hot water is also used in bottles for compressing the body. if the water specific heat Had it been less, the sea water would have evaporated soon.

During the day the air moves from the sea towards the land and in the night the air moves from the land to the sea. This is the reason that the places near the sea do not get too hot nor too cold. Therefore, the weather of the coastal areas is pleasant.

The winds blowing from the sea towards the earth during the day are called ‘sea breeze’ and in the night the winds blowing from the earth to the sea are called ‘Terrestrial Breeze’ it is said.
