Activity 2 1-19-11 Weather and Bemouli Principle

Describe some common weather occurrences in relation to the gas laws and characteristics we have been exploring.

• we need not make any assumption as to whether the particles are molecules and/or individual atoms (av8n.com)
• humid air is less dense than dry air (warm, therefore further apart)
• weather phenomena are actually gas laws and phase changes at work
• the most important gas sample to our existence as aerobic machines is the Earth's atmosphere

What is the Bernoulli Principle, provide an example or application of this.

Bernoulli's principle states that for an inviscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. It is the statement that an increase in the speed of a fluid produces a decrease in pressure and a decrease in the speed produces an increase in pressure.
