The boiling point. The process is condensation, but condensation and boiling occur at the same temperature since the boiling point represents the temperature at which gas and liquid are in equilibrium with each other.
At standard atmospheric pressure of 1 atmosphere or ~100kPa the boiling points of the main constituent gases of air are:
Carbon dioxide solidifies directly from a gas at -78 °C. For it to liquefy the pressure must be >5.1 atmospheres (~520kPa).
Answer 2Here is a list of all the boiling and freezing points of gases in the air::Name Boiling Point Freezing point
It's different for every gas. It also depends on the pressure. You actually need a two-dimensional depiction called a phase diagram. Check out the Wikipedia article on 'vapor'. You also need to consider that most substances will have a non-zero vapor pressure at temperatures below their boiling points and at least down to their freezing points. As long as you're not interested in some pedantic definition of gas which differentiates it from vapor, there is no specific temperature at which a gas turns to liquid, or vice versa.
answ2. A gas turns into a liquid at its condensation temperature, or in the reverse direction, a liquid turns into a gas at its boiling point.
A gas liquefies (changes to a liquid) when it is cooled to a temperature called its boiling point .
Helium
Because the liquid evaporates and turns into gas at a certain temperature
First you can not add a cold temperature to anything. Ask your teacher to explain what heat is an what temperature is, because you clearly do not understand this. When a liquid BOILS - it turns into gas. When a liquid FREEZES - it turn into a solid.
That depends upon temperature and pressure. At room temperature and sea level pressures, most waxes are solid or if you melt it it turns in to a liquid but if you put it at 100 degrees it turns in to gas.
When a liquid turns into a gas
the temperature at which a liquid turns into a gas is called the boiling point.
the temperature at which a substance in the liquid state becomes a gas is a boiling point
Helium
the boiling point
The same as with non-metals. The temperature at which liquid turns to gas, or gas to liquid.
This temperature is called condensation or liquefaction point.

The temperature at which it turns into a gas (usually the temperature when the liquid phase "bubbles" and vaporizes) also the temperature where the gas phase condenses to a liquid.
That depends upon temperature and pressure. At room temperature and sea level pressures, most waxes are solid or if you melt it it turns in to a liquid but if you put it at 100 degrees it turns in to gas.
