Presentation transcript:

Aim: What is Avogadro’s hypothesis? (and application of gas laws.) Essential Questions: Why are the ideal conditions for gases low pressure and high temperature? Describe how you would prove that gases are matter. “Nowhere around you is the absence of air.” Explain this statement using your knowledge of gas behavior. Equal volumes of different gases under the same conditions of temperature and pressure have the same number of molecules. Explain. (Hint…next Q) Why are gases compressible?

Aim: What is an ideal gas and how to apply the gas laws to solve problems? Predict what would happen to the size of a balloon if the gas inside was heated. Explain observations relating to “balloon on hot plate demo.” Describe relationship between temperature of a confined gas and its volume.

Aim: What is Avogadro’s Hypothesis? (and application of gas laws) Gases take up space because… Gases are a form of matter and matter takes up space What are some properties of gases? Gases diffuse rapidly Gases exert pressure Gases fill their container completely Gases are compressible

Aim: What is an ideal gas and how to apply the gas laws to solve problems? Explain how a mercury barometer works. How are the units of pressure related to each other? Why would you rather have a person wearing shoes step on your hand than a person wearing ice skates? Explain in terms of pressure. Explain illustration on handout comparing air pressure at sea level and atop Mt. Everest.

Aim: What is an ideal gas and how to apply the gas laws to solve problems? Why are gases compressible? Describe relationship between pressure exerted on a confined gas and its volume. Why are weather balloons only filled partway with Helium gas? Predict what would happen if weather balloons were completely filled. Why are motorists advised to check their tire pressure as it gets cold in the winter? Why does the mass, and therefore the number of particles, remain constant even though temperature and pressure may be changing? Explain.
