true or false or sometimes true?
1.halving the number of particles in a given volume of gas decreases the pressure by one half, if temperature is kept constant?

2.reducing the volume of a container of gas by one half, has the same effect on pressure as reducing the quantity of the gas in the container by one half, if temperature is kept constant.

3.according to kinetic theory, the particles of an ideal gas have no volume and are not attracted to each other.

4.a balloon with volume of 60l at 1atm pressure will expand to a volume of 120L at a pressure of 0.5atm.

5.Charles law concerns a direct proportion between volume and kelvin temperature and can be represented on a graph as a straight line.

6.According to the combined gas law, T2=P1XV2XT1
P2XV1

7. the ideal gas law allows us to solve for the number of moles of a contained gas when p,v and t are know.

8. the variable for the number of moles is m in the ideal gas law.

9. as the temp. of gas in a balloon decreases the volume increases.

10. gas pressure decreases when more gas molecules are added to a fixed volume container.
