In a gas that contains N molecules, is it accurate to say that the number of molecules with speed v is equal to f(v)? Is it accurate to say that this number is given by Nf(v)? Explain your answers.
Solution 26DQ Step 1: Number of molecules present in the gas is N. For ideal gas the speed of all molecules is not the same. Since molecules are in random motion and they collide each other and walls of the container, speed could not be equal.
