It depends what gas you are taking about liquid helium, it is the coldest we have gotten it, is -270 Celsius.
This temperature is called the boiling point.
It all really depends where the gas is. For water it is 100 degrees Celsius.
The melting point is the temperature at which a solid becomes a liquid.
a gas it becomes a gas at -42 C room temperature is 20 C
When its temperature falls below the boiling point.
Methane, at minus 170 degrees C, or at minus 170 degrees F, is a gas. It is a solid below -182.5 oC (-297 oF) It melts at that temperature and becomes liquid. Liquid methane boils at -161.6 oC (-259 oF) and becomes its form we may be more familiar with, gas.
Generally speaking - if you lower the temperature of a gas, it becomes more dense. If the temperature is lowered sufficiently it will start to condense into a liquid.
the temperature at which a substance in the liquid state becomes a gas is a boiling point
The temperature decreases
This temperature is the boiling point.
This temperature is the boiling point.
aldehyde is a gas/liquid because if you spin this element in a test tube it becomes room temperature
The melting point is the temperature at which a solid becomes a liquid.
a gas it becomes a gas at -42 C room temperature is 20 C
The temperature in which a gas becomes a liquid
When its temperature falls below the boiling point.
No, mercury does not become solid in hot temperature and liquid in coolest temperature. But mercury becomes gas or liquid in hot temperature and becomes solid in coolest temperature. Mercury becomes solid after freezing point of -38.72 degrees Celsius. Solid Mercury can become superconductor in reaching of its critical temperature 4.2 K. Mercury is liquid under the room temperature (25 degrees Celsius). Mercury becomes gas after boiling point of 357 degrees Celsius.
hi.. tehe, its called evaportion
The change between solid, liquid and gas is known as a change of state and is affected by the substance and its temperature. E.g. at room temperature water is liquid but a 0oc it becomes ice, a solid.
