Activity 2 1/19/11 Weather and Bernoulli Principle

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

                When temperature increases, volume increases; this applies when the sun produces heat, causing temperature to increase which causes the expansion of the molecules to increase (volume) which creates wind. When temperature decrease, volume decreases; this applies when clouds cover up heat making the air cooler and wind is being forced in an area (contraction).

                Global Warming: increase in world’s temperature caused by additional heat being trapped by greenhouse gases. Inverse relationship: temperature increases, volume decreases.

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

                Bernoulli Principle states that a fluid’s flow (that has no viscosity (not thin or thick)), has an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or decrease in the fluid’s potential energy. So when the pressure of a fluid decreases the speed of the fluid increases. High-speed flow is associated with low pressure, and low-speed flow is associated with high pressure.
