How Much Pressure? Q - A balloon is filled with pure oxygen. What is the pressure of the oxygen in the balloon? A - Atmospheric pressure. If it wasn’t, then the balloon would expand or shrink. Q - A windbag is blown up with exhaled air. What is the pressure of oxygen in the bag? A – Around 16 - 21% of atmospheric pressure (O 2 is 16% of exhaled air, 21% of atmosphere) Q - A solid container is filled with pure oxygen. What is the pressure in the container? A - It could be anything. The container is solid and therefore cannot shrink or expand.
Dalton’s law of partial pressures Read pages 460 - 461 1.In the 18 th century what did many scientists believe about the earth’s atmosphere? 2.The % of which component of air varies the most? 3.Argon makes up about 0.93% of dry air. List the other 3 gases present in dry air (with their %s). Around what % of dry air is made up by gases other than these 4? 5.1 L of N 2 at 50 kPa is mixed with 1 L of O 2 at 60 kPa, to form a 1 L mixture of the gases. What is the resulting pressure? What are the partial pressures? 6.A balloon contains 75 kPa N 2 , 15 kPa O 2 , 5 kPa CO 2 , and water vapour. If atmospheric pressure is 100 kPa what is the partial pressure of water vapour?
