Lecture 1510/5/05 Research club Friday 11:30 am

A scuba diver taking photos of a coral reef 60 ft below the ocean surface breathes out a stream of bubbles. What is the total gas pressure of the bubbles at the moment they are released? What is the pressure when the bubbles get to the surface?

Name 3 ways the volume occupied by a sample of gas can be decreased.

IDEAL GAS LAW

A 1.00 g sample of water is allowed to vaporize completely inside a 10.0-L container. What is the pressure of the water vapor at a temperature of 150˚C?

Gas Density

Calculate the density of dry air at 25˚C and 1.00 atm if its molar mass (average) is g/mol.

Prove that putting Helium in a balloon will make it rise.
