AP CHEM FINAL EXAM | Complete Updated Answered Solution guide 2023. 6.1 For a classroom demonstration, a chemistry teacher puts samples of two different pure solid powders in a beaker. The teacher places the beaker on a small wooden board with a wet surface, then stirs the contents of the beaker. After a short time the students observe that the bottom of the beaker is frozen to the wood surface. The teacher asks the students to make a claim about the observation and to justify their claims. W...

Geostationary Satellites (Goes) Stationary with respect to a fixed point on Earth's surface (revolves at the same rate as Earth) -Far from earth (36,000 km) = coarse spatial resolution, but good temporal sampling. Visible satellite appears black where the sun is not hitting earth. See lots of black Infrared satellite shows a picture of the whole earth- also shows white around the whole earth. reads the surrounding temp of earth, so the universe is cold, shoing white. ...
