Question

how can you determine the state of an element at room temperature given melting and boiling point?

Answer 1

I don't know what you really mean, but I try (:

Boiling point is the point (temperature) when the object is turning from liquid to gas form
Melting point is the point (temperature) when the object is turning from solid to liquid form.

So if the melting point is higher than the room temp, the object would be in solid form
If the melting point is lower than the room temp, the object could be liquid or gas, you need to check the boiling point
If the boiling point is lower than the room temp, the object is in gas form
If the boiling point is higher than the room temp, it's in liquid form.

-------------------------------> temperature increases
solid - melting point - liquid - boiling point - gas

Answer 2

thanks so much, that was exactly what i meant :)
