Answer:
A) the same B) the same C) 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: , where R is the ideal gas constant, T is the temperature and 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 , 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.
, due to rate is greater than 1 .
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.
