This would be known as its boiling point because it is at the same point as when a liquid turns into a gas. Each substance has a different boiling point, for example, water's boiling point is 100oc.
Boiling - when the liquid is heated to a gas. Evaporating - when the air temperature is hotter than the surface of the liquid so the water turns into water vapor or a gas.
If any liquid gets hot enough, it will turn into gas. The point that it turns into gas varies for each substance.
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.
Different liquids will vaporize at different temperatures.
The temperature is its melting point when from solid to liquid, and its boiling point when from liquid to gas. These temperature points also depend on pressure.
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
the boiling point
Helium
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.
Because the liquid evaporates and turns into gas at a certain temperature
yes
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.
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.
