What is specific heat in chemistry class 11?

What is specific heat in chemistry? The amount of energy needed to increase the temperature of 1 gram of a material by 1 °C is known as its specific heat.

What is the chemistry behind high specific heat?

When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius.

What is specific heat of a substance Class 12 chemistry?

Specific heat, Csp, is the amount of heat required to change the heat content of exactly 1 gram of a material by exactly 1°C.

Is heat capacity and specific heat the same?

Summary. Heat capacity is the amount of heat required to raise the temperature of an object by 1oC. The specific heat of a substance is the amount of energy required to raise the temperature of 1 gram of the substance by 1oC.

What are the chapters in thermal physics class 11?

What is First Law of Thermodynamics class 11?

The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed.

Is specific heat a chemical property?

Specific heat is a physical property.

What does specific heat relate to?

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.

How do you find the final temperature?

Add the change in temperature to your substance’s original temperature to find its final heat. For example, if your water was initially at 24 degrees Celsius, its final temperature would be: 24 + 6, or 30 degrees Celsius.

What is CP and CV?

Cp is “Specific Heat in constant pressure”.This means it is the amount of heat required to increase temperature by 1 dgree celcius, when heat is given at constant pressure. Cv is “Specific heat in constant volume”.

What is the principle of calorimetry Class 11?

Calorimeter Principle The principle of calorimetry indicates the law of conservation energy, i.e. the total heat lost by the hot body is equal to the total heat gained by the cold body.

What is latent heat Class 11?

Latent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance. It could either be from a gas to a liquid or liquid to solid and vice versa. Latent heat is related to a heat property called enthalpy.

What is meant by thermal capacity?

Thermal capacity is defined as the quantity of heat necessary to produce a unit change of temperature in a unit mass of a material.

Is temperature a measure of kinetic energy?

Temperature is a measure of the average kinetic energy of the particles in a substance. It is the kinetic energy of a typical particle.

What is the difference between thermal conductivity and specific heat capacity?

Thermal conductivity describes the ability of a material to conduct heat, and the specific heat capacity tells how much heat energy is absorbed or released depending on the temperature difference and mass [1].

What is the second law of thermodynamics in chemistry class 11?

The second law of thermodynamics states that any spontaneously occurring process will always lead to an escalation in the entropy (S) of the universe. In simple words, the law explains that an isolated system’s entropy will never decrease over time.

What is entropy in chemistry class 11?

Entropy: A measure of the unavailable energy in a closed thermodynamic system that is also usually considered to be a measure of the system’s disorder.

What is the second law of thermodynamics in chemistry?

The second law of thermodynamics describes the nature of processes and chemical reactions as follows: processes occur spontaneously if and only if by their process, the entropy change in the universe, is greater than or equal to zero.

What are the 5 chemical properties?

Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.

What are the 3 physical properties?

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

What is property in chemistry?

What is a chemical property? A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.

What are the different types of heat capacity?

1 Answer. The two types of heat capacities are heat capacity at constant pressure (Cp) and heat capacity at constant volume (Cv).
