In an air-water vapor mixture at 30°C, the partial pressure of the water vapor is 1.7 kPa and the partial pressure of the dry air is 100.5 kPa. The saturation pressure for water vapor at 30°C is 4.00 kPa. What is the relative humidity of the air-water vapor mixture in percent?

Tire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire. C.Tire pressure has increased because there is an increase in kinetic energy of the…
