A 2.0 liter container of nitrogen had a pressure of 3.2 atm. What pressure would be necessary if the volume was changed to 6.4L?

Intensive properties are the properties which values doesnt change with the amount of mass or material that you have, example density, melting point boiling point, molecular mass

Extensive are properties that depends of how much mass or material you have. Example: mass, number of moles, volume, pressure, number of students, population, 

mass, volume, quantity (there is only one of each), color, reflect light, temperature, energy
