If iodine melts at 114 degrees Celsius and boils at 184 degress Celsius what is its physical state at 250 degrees Celsius?

Answer 1

The answer is in the question

Everything can be a solid, liquid or a gas. Below 114'C Iodine is solid, at 114'C it melts and becomes a liquid. Then at 184'C Iodine boils and becomes a gas, therefore above 184'C it is a gas.

This is assuming that the pressure stays constant. Usually if you raise the pressure the boiling and melting point drop. For example at sea level water will boil at 100'C, on the summit of mount Everest (where the pressure is low) water will boil at 70'C. You can almost imagine the low pressure sucking the water into a gas, and the high pressure squashing it back into a liquid
