What is the heat of evaporation?
The heat of evaporation, also known as latent heat of vaporization, is the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the liquid together.
What heat required to change a substance from a liquid to a gas without a temperature change is defiend as the latent heat called?
The heat required to change a substance from a liquid to a gas without a temperature change is referred to as "latent heat of vaporization." This energy is necessary to overcome the intermolecular forces holding the liquid molecules together, allowing them to transition into the gaseous state. During this process, the temperature of the substance remains constant until the entire liquid has vaporized.
Does changing a gas to a liquid require heat?
Changing a gas to a liquid (condensation) typically releases heat, allowing the gas molecules to slow down and come together to form a liquid. This process involves removing energy (heat) from the gas molecules to make them transition into a liquid state.
How a liquid can be changed to gaseous from below its boliling point without supplying it with heat energy?
A liquid can be changed to a gas below its boiling point by reducing the pressure above the liquid. This process, known as evaporation or vaporization, allows the liquid molecules to escape into the gas phase without adding heat energy. This is how clothes dry outside even on a cool day.
What is the difference between boiling and effervescence?
Boiling happens when you heat a liquid, until it evaporates. Effervscense is some gas that escapes, due to some chemical reaction - but not necessarily due to heat.Boiling happens when you heat a liquid, until it evaporates.

How liquid can change in gas without supplying heat?
it isn't possible.With no heat and water, you have no gas.
Is the transfer of heat by moving liquid or gas called conduction?
No, the transfer of heat by moving liquid or gas is called convection. Conduction is the transfer of heat through a material without the movement of the material itself.
What happens when you heat a liquid it becomes a?
When you heat a liquid, it turns into a gas through a process called evaporation or vaporization. The heat increases the kinetic energy of the liquid particles, causing them to break free from their liquid form and become a gas.

What is the process from a liquid to gas and gas to liquid?
The process from a liquid to a gas is called evaporation, where the liquid absorbs heat energy and changes into a gas. On the other hand, the process from a gas to a liquid is called condensation, where the gas loses heat energy and changes into a liquid. Both processes involve a change in temperature or pressure.
How do Change a liquid from gas to liquid?
You lose heat.
When does matter change state?
when water gains or loses heat, it changes its state. When liquid water gains heat, it changes its state from liquid to gas. It becomes water vapor. When solid gains heat, it melts an changes its state from solid to liquid. When gas loses heat, it condenses into liquid. Gas, to liquid. When liquid loses heat, it becomes solid
When a liquid evaporates to a gas heat is?
When a liquid evaporates to a gas heat is gained. This process is more formally known as boiling.

Is gas to liquid endothermic or exothermic?
The liquid to gas phase transformation (evaporation) is an endothermic process. It requires heat to be accomplished. The gas to liquid phase transformation (condensation) is an exothermic process. The vapor releases heat while condensing into a liquid.
Which gas is liquid at ordinary temperature?
Any liquid can be a gas if you heat it strongly enough.
