The number of molecules is so large that statistical treatment can be applied.

So in 1 liter there are 55 times that, number of molecules.

The number of molecules shed by a human being while walking is relatively small.

However, the critical constants are known for only a small number of molecules.

N is the total number of molecules in the system.

This is because of the large number of molecules involved.

N is the number of molecules in the body.

Also, by removing a significant number of molecules, the actual freezing process takes less time.

The number of molecules in a given gas volume depends on the pressure and temperature.

The number of proteins and other molecules that take part increases during the process.
