Define Dalton's law
A) Dalton's law states that in a mixture of gases, the individual gases exert a pressure proportional to their abundance in the mixture. B) Dalton's law states that at a given temperature, the amount of a particular gas that dissolves in a liquid is directly proportional to the partial pressure of that gas, which underlies the diffusion of gases between capillaries and alveoli, and between capillaries and interstitial fluid. C) Dalton's law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. D) Dalton's law states that at a constant temperature, the pressure of a gas is directly proportional to its volume. E) Dalton's law states that at a given temperature, the amount of a particular gas that dissolves in a liquid is inversely proportional to the partial pressure of that gas, which underlies the diffusion of gases between capillaries and alveoli, and between capillaries and interstitial fluid.
