gas ,solid or liquid

[samjam]

if a has a melting point of 53 and a boiling point of 85 is it solid liquid or gas at room temp?

[bernardo]

It depends on the temperature of the room.  If you mean Fahrenheit, it would probably be liquid unless it was very hot or fairly cold.  If you mean Celsius, it would be solid.

[sddsddean]

I think room temperature is usually accepted as 20C, so assuming your temperatures are in Celsius, it would be solid.

Does it have a name, or are we expected to guess?

I think the element in question here is fluorine, which has a melting point of 53.53K and a boiling point of 85.01K at standard pressure.  Since the Kelvin (K) scale starts at absolute zero (approx. -273�C) these temperatures are well below normal room temperature.  In fact, the standard room temperature of 22­�C corresponds to 295K, so the fluorine here would have long since boiled and become a gas.
