Quick Answer: What Is Latent Heat In Geography?

What are two types of latent heat?

Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling).

These names describe the direction of energy flow when changing from one phase to the next: from solid to liquid, and liquid to gas..

What are three types of latent heat?

latent heat of fusion.Latent heat of vaporisation.Latent heat of sublimation.Latent heat of gas hydrate formation.

What is latent heat in short?

Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling). … In both cases the change is endothermic, meaning that the system absorbs energy.

What is called latent heat?

Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. … The latent heat is normally expressed as the amount of heat (in units of joules or calories) per mole or unit mass of the substance undergoing a change of state.

What is the best definition of heat?

Heat is the form of energy that is transferred between two substances at different temperatures. The direction of energy flow is from the substance of higher temperature to the substance of lower temperature. Heat is measured in units of energy, usually calories or joules.

What is Latent Heat Class 9?

CBSE NCERT Notes Class 9 Chemistry Matter In Our Surroundings. The term latent heat of vaporisation can be defined as the amount of heat needed for the conversion of 1kg of liquid at its boiling point to gas at same temperature. It differs among different liquids.
