Known to be the latent heat of evaporation or latent heat of fusion in case of boiling and in case of freezing respectively.
heat
By adding heat and removing heat.
It is the amount of energy required to change the state of 1kg of a substance with no change in temperature.
Latent heat- the amount of heat required by a system/ substance to change phase. It's also heat absorbed or radiated during a change of phase at a constant temperature and pressure.
A change of state is when a substance shifts from solid, liquid or gas to another state. This happens when heat is removed or added.
Thermal (heat) energy must be added or removed in order to cause a change of state.
To change one state of matter to another, you need to either add or remove heat energy. For example, to change a solid to a liquid, you would need to add heat energy to melt the solid. Similarly, to change a liquid to a gas, you would need to add heat energy to evaporate the liquid.
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
Is the amount of energy that is required to change the temperature of 1kg of a substance by 1 degree Celsius with no state change.
the amount of heat required to change the state from liquid to vapour of unit mass without changing the temperature
The amount of heat that must be removed from steam to change it to a liquid is the latent heat of vaporization of water, which is approximately 2260 kJ/kg at atmospheric pressure. This is the amount of energy required for water to change from a gas to a liquid state at a constant temperature.
Yes, heat energy can change a gas to another state. When a gas absorbs enough heat energy, it can transition to a liquid state through a process called condensation. If even more heat energy is added, the liquid can further transform into a solid state through freezing.
