Below are 3 real life situations. Pick two (2) them and explain ALL the science involved in the scenario. This means describe things like what is happening to the gas/liquid/solid molecules or atoms, which principles or laws are at work, why what is happening is happening, and how you know. At sea level, a pot of water will boil at 100 °C. Suppose you wanted to boil the same amount of water high in the Rocky Mountains. What do you expect the temperature will need to be (generally speaking)? Why? A can of soda sits in a sunny spot on the window sill for several hours. It is then opened at the same time as a cold can of soda from the refrigerator. What happens and why? Weather balloons do not float out into space. They reach an altitude of about 15 miles above the surface (3x the height of Mt Everest) and they burst. Why?
