latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Keeping this in view, what do you mean by latent heat explain with example?
Latent heat of the solid means that amount of heat energy absorbed when 1 kg of a substance changes from solid to liquid at its melting point is called latent heat of fusion of the solid. example : Change if ice into water requires a certain heat level so, that it can broke its compactly arranged particles.
Also question is, what is latent heat and types?
Latent heat is the quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Types: There are three phases of the substance: solid, liquid and gaseous.
What is latent heat by Brainly?
Answer: the heat required to convert a solid into a liquid or vapour, or a liquid into a vapour, without change of temperature.
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 latent heat Class 9?
The heat energy which has to be supplied to change the state of a substance is called latent heat. Latent heat does not raise the temperature.
What is latent heat Mcq?
Latent heat of vaporization is. the amount of heat required to raise the temperature of a 1 kg of a substance by 1 K. the amount of heat required to raise the temperature of a substance by 1 K. the amount of heat required to change the phase of a substance from solid to liquid without any change in temperature.
What is latent heat of water?
A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of melting. At 0°C, liquid water has 334 J g−1 more energy than ice at the same temperature. This energy is released when the liquid water subsequently freezes, and it is called the latent heat of fusion.
What is latent heat SI unit?
The specific latent heat of a substance is the quantity of heat energy required to change the state of a unit mass of a substance. EL=ml where EL is the heat transferred, in joules, m is the mass, in kilograms, and l is the latent heat in joules per kilogram. The SI unit for specific latent heat is Jkg−1.
Why it is called latent heat?
Latent heat, also called heat of transformation, is the heat given up or absorbed by a unit mass of a substance as it changes from a solid to a liquid, from a liquid to a gas, or the reverse of either of these changes. It is called latent because it is not associated with a change in temperature.
