What does an increase in pressure on the surface of water do to the boiling point?
It will raise the boiling point. This why, for example, car radiators have a pressure cap. This causes a rise in the boiling point of the water and it is less likely to boil.
Which metal has boiling point less than boiling point of water?
Gallium has a boiling point of 93°ish F. But mercury is way lower than that. It's a liquid at room temperature.
Why Iodine melting point is above room temperature?
Iodine melting point is above room temperature because its vapor pressure is less than one atmosphere.
Why can't iodine be used to displace bromine from sodium bromide?
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
Will a fuel with a higher boiling point be a better fuel than one with a lower boiling point?
A low boiling point one would be better as it will use less heat and release Co2 into the air. --------------------------------------------------------------------------------------------------------- Twitter @TrolPie
Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
Why group 7 elements get more reactive as you go down the group from fluorine to iodine?
There can not be any reason, because the premise is not true: Group 7 elements become less rather than more reactive from fluorine to iodine.
How abundant iodine is?
Iodine is very less abundant compared to fluorine and chlorine and it is found in seawater also with chlorides,bromides etc and certain forms of marine life also contain Iodine in their systems.Eg Seaweeds

What does a positive iodine look like?
Iodine was discovered by the French chemist Barnard Courtois in 1811. Iodine is a bluish-black, shiny solid. Although it is less reactive than the elements above it in group 17 (fluorine, chlorine and bromine) it still forms compounds with many other elements. Iodine is a non-metal. It's boiling point is 457 K (184 oC) and melting point is 386.6 K (113.5 oC). Iodine belongs to group 7A ,the Halogens. Belongs to period 5 in the Periodic table. Iodine might be used in its pure form, but most of the times it is not used as a pure iodine.

Why does solid iodine vaporise when warmed gently?
Its got weak van der waals forces as it is a simple molecule - these intermolecular forces are weak so require less energy to break, leading it to have a low boiling point.
Will a fuel with a higher boiling point be a better fuel than one with a lower boiling point?
A low boiling point one would be better as it will use less heat and release Co2 into the air. --------------------------------------------------------------------------------------------------------- Twitter @TrolPie
What is the boiling point of mineral water?
Less than 100 degrees
Is sodium chloride having more or less melting and boiling point?
More or less of a melting and boiling point than what? Water? Iron? Hydrogen? More information needs to be provided before this can be answered.
