What Are the Most Common Causes of Gas and Bloating?

Gas expansion is driven by the pressure of gas. Microscopically, the temperature of the gas, that is, the collision velocity between molecules, is expressed as the pressure of the gas on a macroscopic scale. It is directly related to the temperature of the gas. How fast the gas can expand depends on his temperature. The higher the temperature, the faster the molecules fly, and the greater the gas pressure and pressure on the macro scale. So the rate of gas expansion depends on the temperature. The environment (or system) in which the gas expands directly affects the change in temperature.
