If any liquid gets hot enough, it will turn into gas. The point that it turns into gas varies for each substance.
Yes , if it has a melting point it can turn into a liquid... if you wan to know the melting point of lead this is it: 327.5 C
You must either increase the temperature of the liquid or decrease the pressure acting on the liquid (i.e., decrease the air pressure).
Gas is in its state for either or both of two reasons, both leading to the same effect. Either the temperature of the substance is too great to remain at a liquid state, or there is insufficient pressure to keep the molecules together enough to remain a liquid. Both reasons will cause the molecules to spread out, eventually turning into a gas. For a gas to turn into a liquid, either the pressure the substance is under would have to be increased or the temperature decreased, causing the molecules to be pressed together enough to return to its liquid form.
At STP (standard temperature and pressure) it is a gas. It can be made to be a liquid or gas by adjusting the temperature and pressure around it, but at room temperature and one atmosphere of pressure (sea level) it is a gas.
Liquid.
90
This is the boiling point.
Well, it depends which gas you are talking about.
It would turn into liquid.
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.
100C or 212F. It is the boiling point of water, where water turns from a liquid into a gas.
all liquids turn in to gas at a certain temperature
This change of phase is called vaporization.
Saturated gas temperature is the temperature at which a gas would be in equilibrium with the liquid phase of the gas (or with the liquid phase of a component of the gas if it was a gas mixture).
Saturated gas temperature is the temperature at which a gas would be in equilibrium with the liquid phase of the gas (or with the liquid phase of a component of the gas if it was a gas mixture).
Gas turns to liquid when energy is lost. The density of a gas is much less that the density of a liquid. Thus, when energy is lost and the particles of the gas are able to condense, it becomes a liquid.
Liquids absorb energy to turn into a gas. The resulting temperature should be less than the initial temperature.
