It's called the melting point.

Heat of evaporation is the amount of heat needed to convert an amount of liquid to a gas without actually changing its temperature. The same amount of heat is also released when a gas condenses to its liquid form while not changing its temperature.

∙ 14y agoThat completely depends on what you want to change. Ice becomes liquid at 0 degrees Celsius (32 degrees Fahrenheit), for example. Quicksilver turns into liquid at
-38 degrees Celsius (-37 degrees Fahrenheit), and is frozen beneath that degree.

What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
Latent
What humidity is measure of the amount of water vapor that air is holding compared to the amount needed for saturation at a specific temperature?
Realative humidity
What does Turning liquid water into water vapor mean?
Order. Solid, liquid,gas/vapor. So It's when Liquid converts into a gas/vapor.
What is the change a vapor to a liquid?
the change of a liquid ie, water to vapor is evaporation.
Is liquid water a water vapor?
No: Vapor is defined as the gas phase of a substance that is mostly solid or liquid at equilibrium at standard temperature and pressure. Therefore, a liquid itself is never a vapor, but the liquid is in equilibrium with a vapor phase that contains the same chemical substance.
What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
Latent
Vapor pressure increases over a liquid in a closed container until?
Vapor pressure increases over a liquid in a closed container until the amount of vapor molecules rejoining the liquid equals the number leaving the liquid to form vapor. This is the characteristic vapor pressure of the substance.
What is the amount of water vapor in the air compared to to the amount of water vapor needed for saturation at a certain temperature?
Relative humidity.
Is the amount of water vapor in the air compared to the amount of water vapor needed for saturation at a certain temperature.?
Relative humidity.
What Is the amount of water vapor in the air compared to the amount of water vapor needed for saturation at a certain temperature.?
Relative humidity.
How does the different phases of matter transform?
Heat energy causes a solid to melt into a liquid. Further input of heat turns the liquid matter into a gas or vapor.
Does the same amount of water take up the most amount of space as an ice cube or a liquid gas or as water vapor?
Liquid water
What is needed in order for the water vapor to change to liquid water?
It needs to be cooled down to condensate.
What is the differences between relative humidity and humidity?
Humidity is the amount of water vapor present in the air. The relative humidity is the measure of the amount of water vapor present in the air compared to the amount needed for saturation.
How is vapor water different from liquid water?
Water vapor is different from liquid water because water vapor is a gas, and liquid water is a liquid.
When alchohol and mercury boil they both change from a liquid to what?
They change from a liquid to a vapor (gas).
Is gasoline a liquid or a vapor form?
Gasoline is a liquid, gas is a vapor.
