Dalton's Law
The total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas.
The total pressure of a gas mixture is equal to the difference of the partial pressures of each individual gas.
The total pressure of a gas mixture is equal to the product of the partial pressures of each individual gas.
The total pressure of a gas mixture is equal to the average of the partial pressures of each individual gas.
Dalton's Law
The partial pressure of a gas in a mixture is directly proportional to its mole fraction.
The partial pressure of a gas in a mixture is inversely proportional to its mole fraction.
The partial pressure of a gas in a mixture is independent of its mole fraction.
The partial pressure of a gas in a mixture is equal to the total pressure of the mixture.
Dalton's Law
The partial pressure of a gas increases with an increase in temperature, assuming volume is constant.
The partial pressure of a gas decreases with an increase in temperature, assuming volume is constant.
The partial pressure of a gas remains constant with an increase in temperature, assuming volume is constant.
The partial pressure of a gas is unaffected by temperature changes.
