Kinetic-Theory of Gases

Kinetic theory of gases is the model or method which was developed in the 19th century by Maxwell and Boltzmann. This is possible as the interatomic force which is of short-range forces that are important for solids and liquids can be neglected for gases. This theory or gas law gives a molecular interpretation of the pressure and temperature of a gas and is consistent with gas laws and Avogadro’s hypothesis. This theory is very helpful to correctly explain the specific heat capacities of many gases, kinetic energy and it also explains the transport qualities such as viscosity, thermal conductivity, and diffusion with molecular parameters. As stated in the kinetic-molecular theory, the temperature of a substance or gas particle is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles, called average kinetic energy.

Question

100%

**Problem Statement:**

Suppose that in a closed-end manometer the mercury in the closed arm was 14.9 cm higher than the mercury in the arm connected to a vessel containing a gas. What is the pressure of the gas expressed in torr?

**Solution:**

To calculate the pressure of the gas using a closed-end manometer, we start by understanding that the height difference in the mercury column corresponds to the pressure of the gas in torr.

1. **Height Difference:** The height difference given is 14.9 cm.

2. **Pressure Conversion:** In a manometer, the height difference in mercury (in centimeters) can be directly converted to pressure in torr. Therefore, the pressure of the gas is 14.9 torr.

This calculation assumes that the atmospheric pressure is not affecting the closed-end manometer, as one side is sealed, and the given height is the only variable needed to determine the gas pressure.
