Yes, they have. They are gaseous at room temp. but at some temperature they are liquid as well as solid.
For example :- Methane has
Melting point
-182.5 °C, 91 K, -297 °FBoiling point
-161.6 °C, 112 K, -259 °F
No, Gas--->liquid (condensation). Solid---->liquid (melting)
−156.6°C
Chlorine is a gas at room temperature. It's melting point is -101.5°C , and it's boiling point is -34.04°C.
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
It depends on what substance the gas is.
No, Gas--->liquid (condensation). Solid---->liquid (melting)
No, it is the melting point. Ice changes to water when it melts, not when it boils.
The melting point is the temperature at which a solid becomes a liquid.
IT has a low boiling point ha
No, at its boiling point
hydrogen
Boiling point is the temperature point at which a liquid becomes a gas while melting point is the point at which a solid becomes a liquid.
When cooled to below 54.36 K (-218.79 oC , -361.82 oF, oxygens melting point) it will become solid. That's what a 'melting point' is!
only solid state mater can be melt not any gas, but is any gas is compressed to form solid then it can have a melting point and that will be lower then room temprature at atmospheric pressure
−156.6°C
The point at wich a substance melts or turns in to a gas
