The ventilating air currents in the mine also affect the gas s rate of diffusion. The rate of diffusion is greatly increased by higher velocities of air currents or by turbulence in the air. Knowing the effects of air current, temperature, and pressure on a gas will help you determine its rate of diffusion. The rate of diffusion is how quickly the gas will be quickly mix or blend with one or more other gases and ho it can be dispersed. Atmospheric Pressure and Its Effects on Rate of Diffusion- Pressure exerted on a gas is usually atmospheric pressure.
Atmospheric pressure is measured on a barometer.
A rise in the barometric reading indicates an increase in pressure. A drop in barometric reading indicates a decrease in pressure. The atmospheric pressure varies within a mine, just as it does on the surface. Atmospheric pressure affects the diffusion rate of a gas. For example, if the barometer rises, indicating increased pressure, gas responds by contracting.
