Answer:
A) the same B) the same C) [tex]v_{A}>v_{B}[/tex] D) compensation between force and velocity.
Explanation:
A) Avogadro´s law says that at the same volume, temperature and pressure two gases have the same amount of molecules.
B) Kinetic energy can be expressed like this: [tex]E_{k} = \frac{3RT}{2N_{A} }[/tex], where R is the ideal gas constant, T is the temperature and [tex]N_{A}[/tex] is the Avogadro´s number. All this values are the same in both gases thus they have the same kinetic energy.
C) Average velocity is given by the formula [tex]v=\sqrt{\frac{3RT}{M} }[/tex], where M is the molecular mass, if we want to know wich gas has fastest velocity is enough to know the rate between two velocities.
[tex]\frac{V_{A} }{V_{B} } =\frac{\sqrt{\frac{3RT}{M_{A} } } }{\sqrt{\frac{3RT}{M_{B} } } } =\frac{\sqrt{M_{B} } }{\sqrt{M_{A} } } =\frac{\sqrt{\frac{m_{B} }{n} } }{\sqrt{\frac{m_{A} }{n} } } } =\frac{\sqrt{m_{B} } }{\sqrt{m_{A} } } =\frac{\sqrt{0.48g} }{\sqrt{0.34} } =1.2[/tex], due to rate is greater than 1 [tex]v_{A}>v_{B}[/tex].
D) Molecules of gas B are larger, but they have a smaller velocity (collide the walls less times than gas A), by the other hand, molecules of gas A are smaller but they have a higher velocity (collide the walls with higher frequency than gas B), as a result both gases have the same kinetic energy that produces the same pressure.
