2260 kj/kg X 0.086 kg = 194 kj
The heat of vaporization for water is 2260 kj/kg at 1 atmosphere pressure.
Assuming standard atmospheric pressure, 2260 kilojoules.

The thermal energy of a solid or a volume of liquid is the specific heat of a material multiplied by the object's mass and temperature (absolute). I.E. 1 kg of water at 27 degrees C: specific heat of water is 4.186 Kilojoules per kilogram-degree Celsius. Multiply that by the mass and the absolute temperature (Degrees Kelvin, or 273.15 + degrees Celsius) to get the thermal energy in kilojoules

I will use this formula. Some conversion will be required. ( I only know specific heat iron in J/gC ) q(Joules) = mass * specific heat * change in temperature Celsius 3 kilograms cast iron = 3000 grams q = (3000 g)(0.46 J/gC)(120 C - 30 C) = 124200 Joules (1 kilojoule/1000 joules) = 124.2 kilojoules of energy needed ===========================

A balloon filled with -2 degrees Celsius air will move to a room to a temperature of 8 degrees Celsius because of the collision of the air particles.
