If a sample of gas occupies 6.8 l at 327 C what will be it's volume at 27•C if the pressure and number of particles do not change ( P and n= constant)

they should be similar or the same

pe = weightxheight = 2000x1000=2,000,000joules

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d

overcharge is the right answer system
