Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
The melting point of copper is 1 084,62 oC.The melting point of iodine is 113,7 oC.The melting point of naptalene is 78,2 oC.
The melting point is the temperature which a material, element or mixture, changes from the solid to a liquid. Therefore, all liquids become solids above the melting point.
Some do while others do not. To be solid a substance must merely have a melting point that is above room temperature. Gallium has a melting point just above room temperature, so it is normally solid but it will melt in the palm of your hand. By contrast Tungsten has such a high melting point that not even the hottest lava from Earth's volcanoes can come close to melting it.
The boiling point of a substance is the point at which that substance will change between being a gas and a liquid. For example, the boiling point of water is 100oC, so water vapour will change to water at this temperature. The boiling point of Methane is -161oC, so any temperature above this, Methane will be in gas form.

is the temperature if the stiffer mantle above or below its melting point
When a material is melting, the temperature is likely to be increasing. That or the temperature is just above the material's melting/freezing point.
If the temperature is below the melting point, you know it is in the solid state. If the temperature is below the boiling point, and above the melting point, you know it is a liquid. If the temperature is above the boiling point, you know it is a gas, etc. (Note: melting point is the same as freezing point).
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
is the temperature if the stiffer mantle above or below its melting point
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.
