1. Aim: How does a change in temperature affect pressure of a confined gas? (Gay-Lussac’s law) Essential Questions : Why are motorists advised to check their tire pressure as it gets cold in the winter? Why are there warnings on sealed spray cans indicating that user not store in a place where temperatures exceed a given temperature? Describe relationship between temperature of a confined gas and its pressure. Why does the mass, and therefore the number of particles, remain constant even though temperature and pressure may be changing? Explain. “Nowhere around you is the absence of air.” Explain this statement using your knowledge of gas behavior.
