What are the uses of specific heat?

Specific heat gives the amount of heat energy 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.

What is the specific heat of a gas?

The specific heat of a gas at constant pressure is the amount of heat required to raise the temperature of one mole of a gas by unit temperature at constant pressure.

What are the three uses of specific heat of water in daily life?

Explanation: Fomentation: Hot water bottles are used for fomentation, as the water remains hot in the bottle for a long time in spite of giving off large quantities of heat. Car radiators: Water is used as coolant car radiators. Bottled Wines: In cold countries, wine bottles re kept under water.

What is specific heat and how is this energy being used?

specific heat: The ratio of the amount of heat needed to raise the temperature of a unit mass of substance by a unit degree to the amount of heat needed to raise that of the same mass of water by the same amount.

What is specific heat of gas and its types?

In other words, all the amount of heat supplied remains within the body of the gas, and represents the increase in internal energy of the gas. 2. Specific heat at constant pressure. It is the amount of heat required to raise the temperature of a unit mass of a gas through 1°, when it is heated at constant pressure.

What is meant by specific heat of gas and give its types?

specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. See also heat capacity.

What are the specific uses of heat in industry and into your daily life?

Heat is used to make things warm, to boil water and fry eggs and to melt metal to build cars. Heat is used to generate electricity at a thermal power plant for our daily lives.

What are the applications of high specific heat of water?

Water is used as coolant car radiators for its high specific heat capacity, due to which it can absorb a large amount of heat energy from the engine of the car, without its temperature rising too high.

How is specific heat capacity used in everyday life?

Uses of specific heat in daily life Substances having a small specific heat capacity, are very useful as material in cooking instruments such as frying pans, pots, kettles and so on, because, when small amount of heat is applied it will heat quickly. Water used in fire fighting.

How does specific heat affect heat transfer?

Specific heat of a substance is the amount of heat energy reuired to raise its temperature. So if we compare, the temperature of sand rises very fast as compared to water. It means sand requires less heat energy to have a rise in temperature. Hence you can conclude that water has a higher specific heat.

What is the specific heat of gas in isothermal process?

zero
The specific heat of a gas in an adiabatic process is zero but it is infinite in an isothermal process.

Why there are two specific heats of gas?

A solid or a liquid when heated, does not undergo any change in the volume or pressure. But in case of a gas, both the pressure and volume change on heating. Therefore, specific heat of a gas is defined either at constant volume or at constant pressure and hence a gas has two specific heats.

Why do we define two specific heats of gases?

Hence it is necessary to define two specific heats of gases. viz. Specific heat at constant pressure and specific heat at constant volume. The quantity of heat required to raise the temperature of one mole of gas through 1K (or 1 °C) when the volume is kept constant is called molar specific heat at constant volume. It is denoted by C V.

How do you fix the specific heat of a gas?

Due to which the specific heat of gas can have any value between 0 and ∞. Therefore to fix the values of specific heat of a gas, either the volume or pressure is kept constant.

What is the specific heat capacity of an ideal gas?

The specific heat (= specific heat capacity) at constant pressure and constant volume processes, and the ratio of specific heats and individual gas constants – R – for some commonly used “ideal gases”, are in the table below (approximate values at 68oF (20oC) and 14.7 psia (1 atm)).

What are the three components of specific heat?

Specific heat at constant volume, specific heat at constant pressure, specific heat ratio and individual gas constant – R – common gases as argon, air, ether, nitrogen and many more .. Sponsored Links.
