A sample of nitrogen gas in a 4 L container at 500 mmHg is moved into a 10 L container. An 8 L sample of oxygen at 900 mmHg is moved into the same 10 L container. What is the total pressure of the 2 gases in the 10 L container?

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
