Partial pressure refers to the pressure exerted by a single gas in a mixture of gases. It is calculated by multiplying the total pressure by the mole fraction of the gas in the mixture.
Partial pressure can be calculated using the formula P = nRT/V, where P is the partial pressure, n is the number of moles of the gas, R is the ideal gas constant, T is the temperature in Kelvin, and V is the volume of the container.
The sum of all partial pressures in a gas mixture is equal to the total pressure. This is known as Dalton's law of partial pressures.
According to the ideal gas law, an increase in temperature will result in an increase in the partial pressure of a gas, assuming the volume and number of moles remain constant.
If the number of moles and temperature remain constant, decreasing the volume of a container will increase the partial pressure of a gas. This is because the molecules are more confined and collide more frequently with the container walls, resulting in a higher pressure.
