The melting points and boiling points of some elements are given below. Classify their states – solid, liquid or gas – at room temperature (25°C). For an extra challenge, work out their states at 2000°C.ElementMelting point (°C)Boiling point (°C)State at room temperature (25°C)State at 2000°Chelium-272-269gasgasiron15382861bromine-759boron20774000mercury-39357aluminium6602519fluorine-220-188

Please note that the state of an element at a given temperature depends on whether the temperature is above or below the element's melting and boiling points. If the temperature is below the melting point, the element is a solid. If it's between the melting and boiling points, it's a liquid. If it's above the boiling point, it's a gas.
