A gas condenses into liquid phase if its cooled below its critical temperature
and pressurized. If pressure is above the gas triple point pressure, cooling
is enough to condense the gas to liquid phase.
A gas below its critical temperature is called a vapour.
Sublimation is when a solid turns into a gas. E.g Dry ice is a solid but slowly turns into a gas, it doesn't go into a liquid. Evaporation is liquid to gas.
The energy needed to go from a liquid to a gas is referred to as heat of vaporization.
gas to liquid = condensation liquid to solid = freezing the gas must go through a liquid state, Even if for a millisecond.
Any amount of time
Changes from a liquid to a gas
The energy required to go from liquid to gas is known as the heat of vaporization. It represents the amount of energy needed to convert one unit of a substance from liquid to gas at its boiling point. The heat of vaporization varies for different substances and is typically expressed in units of joules or calories per gram.
The states of matter are solid, liquid and gas. A solid melts to become liquid and a liquid evaporates to become gas. Sublimation is the direct change from solid to gas.
Go to the bank of any river. The air is the gas, the water the liquid and the dirt on the bank is the solid.
Well go buy a bottle and you will see it is a liquid! x

False. Solids cannot go directly into the gas phase without becoming a liquid first. This process is known as sublimation, where a solid turns into a gas without passing through the liquid phase.
Yes. Ice can melt from a solid to a liquid and then the water (liquid) evaporates into a gas and goes up into the air.
