that equal volumes of gas under the same conditions have equal numbers of molecules. This concept is a very important one, as it

will be used often in future studies.

<u>Answer:</u>

Avagadro’s law states at constant temperature and pressure, volume is directly proportional to the number of molecules of the gas.

For example  

At STP that is standard temperature and pressure at which T = 273K and P = 1 atm

Volume occupied by 1 mole (6.022\times 10^{23} gas molecules) of any gas is equal to 22.4L

That is

1 mole = 22.4L

2 mole = 44.8 L

3 mole = 67.2 L

So 1 mole of CO_2 gas =22.4L (6.022\times 10^{23} gas molecules)

1 mole of H_2 gas =22.4L (6.022\times 10^{23} gas molecules)

1 mole of Cl_2 gas =22.4L (6.022\times 10^{23} gas molecules)

Answer:

This one is easy. It's the Avogadros' Hypothesis or Avogadros' Law, where the equal volumes of gases in SAME conditions have an equal amount of molecules!

Cylinder D
temperature is the measurement of average kinetic energy of a sunstance. since cylinder D has the highest average velocity, it has the highest average kinetic energy among the 4 cylinders, thus cylinder D is the hottest.
