It's called the melting point.

What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
The amount of heat needed to change 1 kg of a material from liquid to vapor at a constant temperature is called the latent heat of vaporization. This value varies depending on the material and is typically provided in joules/kg.
What occurs when heat energy is removed from a liquid-vapor system in equilibrium?
When heat energy is removed from a liquid-vapor system in equilibrium, the temperature of the system decreases, leading to a shift in the equilibrium position. According to Le Chatelier's principle, the system will respond by favoring the exothermic process, which in this case is the condensation of vapor into liquid. As a result, more vapor will condense, increasing the amount of liquid while decreasing the vapor phase until a new equilibrium is established.
What is the change a vapor to a liquid?
The change from a vapor to a liquid is called condensation. This occurs when vapor cools down and loses energy, transforming into liquid droplets.
What happens to the system in which the contained liquid evaporates at room temperature?
As the liquid evaporates at room temperature, the system will experience a decrease in the amount of liquid present and an increase in the amount of vapor in the container. This will result in a change in the pressure and temperature within the system as the liquid continues to evaporate.
What is the temperature at which water in the air changes from a gass to a liquid?
The temperature at which water vapor changes from a gas to a liquid is called the dew point. This varies depending on the amount of water vapor present in the air.
What is the amount of heat needed to change 1 kg of a specific material from liquid to vapor at a constant temperature?
The amount of heat needed to change 1 kg of a material from liquid to vapor at a constant temperature is called the latent heat of vaporization. This value varies depending on the material and is typically provided in joules/kg.
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
Is it true condensation occurs when water vapor is heated?
No, condensation occurs when water vapor is cooled and changes from a gas to a liquid. Heating water vapor would cause it to remain in its gaseous state or potentially transform into steam, which is still a gas.
What is needed in order for the water vapor to change to liquid water?
It needs to be cooled down to condensate.
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.
How much liquid argon do you need for twenty pounds of argon gas?
To convert from pounds of gas to liquid, you need to know the vapor pressure of the gas at the expected temperature. Without this information, it isn't possible to determine the exact amount of liquid argon needed.
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.
What is the rate of condensation formula used to calculate the amount of water vapor that changes into liquid per unit time?
The rate of condensation formula is used to calculate the amount of water vapor that changes into liquid per unit time. It is typically expressed as the mass of water vapor condensed per unit time.
