The amount of heat absorbed by 1 kg of liquid to vaporize it depends on what that liquid is, (water?), and what the temperature of the liquid is at the start of the process. Obviously, it will take more heat to vaporize 1 kg of liquid that is at 0º than it will to vaporize 1 kg of liquid that is at, say, 30º.

That depends on what you are trying to ask.First point is that heat is energy in transit - if it isn't moving from one place to another it's technically not heat. Thermal energy - the energy held by a mass due to temperature is a better term, but even that is a bit ambiguous.With that in mind...if you mean how much energy can be stored as thermal energy by aluminum, you would have to look up the heat capacity - which is approximately 0.91 kJ/kg K (the exact value depending on temperature and purity of the aluminum)If you mean how much resistance aluminum foil can provide to the transfer of heat, that would depend on the temperature gradient and how shiny the aluminum was - shiny aluminum will reflect more heat that dull/burnished aluminum surfaces.
The specific heat for aluminum is 0.9 J/g/degree and you use the equation of q = mC∆T.q = (30.0 g)(0.9 J/g/deg)(50 degrees) = 1350 J 0r 1.35 kJ

The boiling point of ethanol is 78 C but it can evaporate slowly at just room temperature. You can set it on fire and it will vaporize even more quickly.

The latent heat for water to steam is 550 calories (2310 Joules) per gram. For 2 grammes, double these figures.
