heatof vaporization
The term for the amount of energy required for a liquid at its boiling point to become a gas is called the latent heat of vaporization. This energy is needed to overcome the intermolecular forces holding the liquid molecules together and allow them to escape as a gas.
The amount of energy required for 1 kg of a liquid at its boiling point to become a gas is known as the latent heat of vaporization. This energy varies depending on the liquid; for water, it is approximately 2,260 kJ/kg. Thus, to convert 1 kg of water at its boiling point to steam, you would need about 2,260 kJ of energy. Other liquids have different latent heat values, reflecting their unique properties.
Yes, energy is required for a liquid to change into a gas. This process is known as vaporization or boiling and it requires the liquid to absorb heat energy to overcome intermolecular forces and become a gas.
No, the heat of vaporization is the amount of energy required to change a substance from a liquid to a gas, while the boiling point is the temperature at which a substance changes from a liquid to a gas.
The latent heat of vaporization
The amount of energy required to turn a mole of a liquid into a gas
Energy is required in the melting process because high is needed to melt something
At low pressure, less energy is required for molecules to escape the liquid phase to become gaseous. Conversely, at high pressure, the boiling point is increased.
The heat of fusion is the amount of heat (not temperature) required to change a solid to a liquid. It is also known as the melting point. The heat of vaporization is the amount of heat (not temperature) required to change a liquid to it's gaseous state. It is also know as it's boiling point.
Melting requires energy input or absorption because liquid water has more energy than solid water.
Activation energy in chemistry is the amount of energy required to start a reaction. For every chemical reaction, a certain amount of energy is required to start it
During boiling, the amount of energy remains constant as the temperature of the substance stays the same until all of it has converted into vapor. Once boiling starts, the added heat energy is used to break the intermolecular bonds holding the liquid together, rather than increasing the temperature.
