Chlorine is more electromagnetic than bromie, the C-Cl bond is more polar than the C-Br. The permanent dipole is stronger between 1-chloropropane molecules, so more energy is required to break these intermolecular bonds. The boiling point of 1-chloropropane is higher than 1-bromopropane.
Butane because it contains more atoms and is heavier.
The boiling point of chlorine is -34.6 degrees C and the boiling point of iodine is 184 degrees C so iodine's boiling point is massively higher
Lead(II) sulfate melts at over a 10000C. I can't find a boiling point and I am not surprised- I would expect decomposition at such temperatures.

Hydrogen bonding is a weak electrostatic attraction between a covalently bonded H on one atom with an electronegative atom in another molecule. In water this is a bond between the H of one H2O molecule and the O of another. The effects are remarkable. Boiling point and melting point are much higher than you'd expect (compare H2S) the density of ice is lower than that of liquid water.

I'd expect this to be negligible. The molecules which do bind to haemoglobin are oxygen, carbon monoxide and nitric oxide.
it's larger
Any solvent can; the more ions it dissipates into, the more it will change the boiling point (in general). You shouldn't expect a very large change, however. Pressure tends to affect boiling point more than solvents.
The solute in a solution modify the boiling point of water.
Physically I would expect to find the same boiling and melting points, and the same density. Chemically, I would expect the same reactivity with other substances.
The answer depends on the volume of the gas in the tank, temperature and the dimensions of the tank. As a rule of thumb, you could expect to develop 6,000,000 btuh at 40*
Metahne does not have a higher boiling point than methane. Fluoromethane, CH3F, has a boiling point of 195K, -78.2C, methane, CH4, has a boiling point of 109K approx -164 C. I make that fluoromethane has a higher temeprature boiling point than methane. This is what you would expect, London dispersion forces will be greater in CH3F as it has more electrons than CH4. CH3F is polar and there will be dipole dipole interactions which will not be present in CH4.
They have a higher boiling point and lower melting point and is flamable.
