What are the factors affecting mean free path?
Density: As gas density increases, the molecules become closer to each other. Therefore, they are more likely to run into each other, so the mean free path decreases.Increasing the number of molecules or decreasing the volume will cause density to increase. This will decrease the mean free path.Radius of molecule: Increasing the radius of the molecules will decrease the space between them, causing them to run into each other more. Therefore, mean free path decrease.Pressure, Temperature, and other factors that affect density can indirectly affect mean free path.
What is difference between path function and point function in thermodyanaMICS?
Path function: Their magnitudes depend on the path followed during a process as well as the end states. Work (W), heat (Q) are path functions.The cyclic integral of a path function is non-zero. work and heat are path functions.Point Function: They depend on the state only, and not on how a system reaches that state. All properties are point functions.The cyclic integral of a point function is zero. properties are point functions, (ie pressure,volume,temperature and entropy).
Is displacement or distance independent of path?
Displacement and overall distance are but the distance travelled does depend on the path.
What is path or state quantity?
State quantities are dependent on path,and path quantities do not depend on path.for example:we want to travel from one city to another and we have different routes to travel by,so the distance traveled depends on that which one route is taken,so the distance traveled is a path quantity,well the city current where we are at times does not depend on the path we took,so it is state quantity
What are some conservative forces?
Gravitational Forces,Magnetic Forces,Spring Forces,Electric Force....... They do not depend on the path followed,they depend on initial and final point of work.

At a constant pressure how does a volume of gas vary with respect to the absolute temperature?
It doesn't. The equation for mean free path is: mfp = 1 / [sqrt(2)*n*pi*d^2] In the above equation, n is the number of molecules per unit volume, and d is what is known as the collision diameter (the distance between the centers of the two colliding molecules). Thus, there are only three variables which affect mean free path: number of molecules, volume, and collision diameter. Volume can be changed by a change in temperature, but this question assumes constant volume (meaning pressure will change as temperature changes). As long as the amount of gas is unchanged, the mean free path will be unaffected by changes in temperature. This is a wrong answer. The collision diameter decreases with the increase of temperature.
What is the measure of how packed molecules are?
mean free path
Mean free path of water molecule?
k
What happens to the mean free path of the molecules in this process if a helium filled balloon initially at room temperature is placed in a freezer will its volume increase decrease or remain the same?
The volume decrease.
How does mean free path depend on pressure of a gas?
I believe the shorter the mean free path, the higher the density. Basically, the closer the molecules are, the more dens it is. That is why when you add pressure, the density goes up ... by this equation. d = PM/RT P=pressure M=molar mass R=gas constant T=absolute temperature Basically, the more pressure put on a gas, the closer it goes to being a liquid... which is denser. The bigger the gas (molar mass) the smaller the mean free path, the denser it is. However, I do not know how to relate mean free path mathematically to density yet.

Does helium conduct heat or electricity?
thermal conductivity of gas is directly proportional to mean free path, mean particle speed and heat capacity. Due to small size and lower mass, helium has high mean free path and mean particle speed; hence has high thermal conductivity.
Is displacement or distance independent of path?
Displacement and overall distance are but the distance travelled does depend on the path.
What is Hesses law?
