Recall that the total pressure of air at sea level is about 1 atm, and that air is 20.9 percent oxygen. What is the partial pressure of oxygen in air? How does it compare to the oxygen in the tank?

The climate of the continental united states is generally 1. tropical 2. temperate 3. arctic 4. highland

24. a sports ball is inflated to an internal pressure of 1.85 atm at room temperature (25 °c). if the ball is then played with outside where the temperature is 7.5 °c, what will be the new pressure of the ball? assume the ball does not change in volume nor does any air leak from the ball a) 0.555 atm b) 1.74 atm c) 1.85 atm d) 1.97 atm

Using the first volume and temperature reading on the table as v1 and t1, solve for the unknown values in the table below. remember to use the rules of significant figures when entering your numeric response.
