The Maxwell distribution function is a probability distribution that describes the speeds of molecules in a gas. Let's analyze each statement:<br /><br />1. The Maxwell distribution function depends on temperature.<br /> - This statement is correct. The Maxwell distribution function depends on the temperature of the gas, which affects the average kinetic energy of the molecules.<br /><br />2. The Maxwell function is zero at $v=0$ and $v=\infty$.<br /> - This statement is incorrect. The Maxwell distribution function is not zero at $v=0$ and $v=\infty$. It is non-zero for all values of velocity.<br /><br />4. Each value of the function $F(v)$, except for the maximum, corresponds to two values of the velocity of molecules.<br /> - This statement is correct. The Maxwell distribution function is symmetric about the mean velocity, so each value of the function corresponds to two values of the velocity.<br /><br />8. The derivative $\frac{dF}{dv}$ is not zero at any speed values.<br /> - This statement is incorrect. The derivative of the Maxwell distribution function is zero at the mean velocity.<br /><br />Therefore, the sum of the statement numbers that correctly reflect the properties of the Maxwell distribution function is 1 + 4 = 5.
