20 POINTS. Explain Dalton’s Law of Partial Pressures.
“The total pressure of a mixture of gases is equal to the sum of the individual (partial) pressures.”

Dalton's Law (also called Dalton's Law of Partial Pressures) states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases. Mathematically, this can be stated as follows: Ptotal=P1+P2+… +Pn. + P n.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
