## What is the specific heat of solids?

In other words specific heat of a solid or liquid is the amount of heat that raises the temperature of a unit mass of the solid through 1° C. We symbolise it as C. In S.I unit, it is the amount of heat that raises the temperature of 1 kg of solid or liquid through 1K.

**What is Einstein theory of specific heat of solids?**

A theory of the specific heat of solids proposed by Albert Einstein in 1906. In this theory, Einstein attributed the specific heat of solids to the vibrations of the solid and made the simplifying assumption that all the vibrations have the same frequency.

### What is the theory of specific heat capacity?

In thermodynamics, the specific heat capacity (symbol cp) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature.

**What is the hypothesis of Dulong Petit law?**

Dulong–Petit law, statement that the gram-atomic heat capacity (specific heat times atomic weight) of an element is a constant; that is, it is the same for all solid elements, about six calories per gram atom.

#### How do you find the specific heat of a solid experimentally?

Procedure – pour a certain amount of water into a calorimeter with both at room temperature. Enclose the calorimeter with wool, wooden box or other poor conductors of heat to reduce heat loss. Now measure an amount of the solid (by mass) and heat it over a Bunsen burner. Measure the temperature of the heated solid.

**How does the specific heat of solids vary with the temperature?**

The average energy increases only from translation. As the substance heats up, the average kinetic energy of the molecules increases. The collisions impart enough energy to allow rotation to occur. Rotation then contributes to the internal energy and raises the specific heat.

## How does the specific heat of solids vary with the temperature explain Einstein’s hypothesis to explain it?

Einstein quantum theory of specific heat When the temperature of the solid is increased, the atoms are set into simple harmonic vibrations about their mean positions with a frequency v, which is characteristic of a solid and is called Einstein’s frequency.

**What is the Einstein temperature?**

[¦īn‚stīn ‚kar·ik·tə¦ris·tik ′tem·prə·chər] (solid-state physics) A temperature, characteristic of a substance, that appears in Einstein’s equation for specific heat; it is equal to the product of Planck’s constant and the Einstein frequency divided by Boltzmann’s constant.

### What is specific heat used for?

Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.

**What is heat capacity state the Dulong Petit law?**

The Dulong Petit Law states that the product of specific heat and atomic mass or gram-atomic heat capacity of an element is always a constant. It is constant for all solid elements. The law was developed in 1819 on the grounds of examinations by Pierre-Louis Dulong and Alexis-Thérèse Petit.

#### Why is the heat capacity of solids limited by Dulong Petit limit at high temperatures?

The Dulong petit limit is as follows: The law is not applicable for light atoms bonded strongly to each other at room temperature. It wrongly predicts a higher heat capacity than found because the energy vibrational modes are not populated at room temperature for these substances.

**Which device you select to measure the specific heat of a solid in the laboratory?**

calorimeter

The calorimeter is a device used to measure the heat flow of a chemical or physical reaction. Calorimetry is the process of measuring this heat.
