Diffusion<span> is defined as spreading of molecules of a substance, away from each other, throughout the space.

Effusion is the phenomena of escape of gas molecules through a very small orifice into an evacuated area.
According to Graham's Law, rate of diffusion and effusion is inversely proportional to molecular mass.
Thus, with increase in molecular mass, rate of diffusion and effusion will decrease.
They are grouped together because they share certain physical and chemical properties. For instance, metals are dense, shiny, good conductors of heat and electricity, and they easily lose electrons in chemical reactions. In contrast, nonmetals have the opposite properties.
That is approximately .63620 grams.
Answer:
Greater the mass
Greater kinetic energy
Velocity
Greater kinetic energy
Mass and velocity
Explanation:
We know that kinetic energy of object
Where m=Mass of object
v=Velocity of object
Kinetic energy is directly proportional to mass and velocity of object.
When mass of object is greater then the object has greater kinetic energy when the mass of object is small then the object has small kinetic energy.
When the velocity of object is greater then the object has greater kinetic energy when the velocity of object is small then the object has small kinetic energy.
The greater the mass of an object moves,the greater the kinetic energy it has.
The greater the velocity of a moving object,the greater kinetic energy it has.
Kinetic energy depends on both mass and velocity of object.
No, because there is a vaccum between earth and the moon (no air) and sound requires a medium to pass to pass through to be heard.
