3 Page 3 of 3 Directions: Complete each question below. 44. Describe molecular motion in Solids Liquids Gases Molecules are slowly moving / vibrating / locked into place Molecules free to move in the container Molecules are moving quickly in many directions 45. Describe air Air has mass and volume. Air has density. Air can be compressed (forced into a smaller space). Air is made mostly of nitrogen (78%) and oxygen (21%). Air gains energy from the Sun and the Earth through radiation, conduction, reradiation and convection. 46. Describe the convection chamber? Smoked entered the chamber and sank to the bottom because the smoke was cold and denser than the air in the chamber. The smoke traveled along the bottom to the lit candle. The smoke was heated, became less dense, and rose. The smoke traveled along the top, losing energy, becoming colder and denser again. This was repeated again and again to create a convection cell.

4 Page 4 of Calculate Density Solution A has a volume of 30 ml and a mass of 47 g. Solution B has a volume of 35 ml and a mass of 42 g. Which solution is denser? A 47g / 30 ml = 1.6 g/ml B 42 g / 35 ml = 1.2 g/ml Solution A is denser. 48. Explain how clouds form. Water is heated by radiant energy from the sun and it evaporates into water vapor. The water vapor travels up through the atmosphere where it begins to cool. The water vapor condenses on a condensation nucleus. The water droplets form clouds. 49. Draw the water cycle. Infiltration

5 Page 5 of Explain how volume, pressure, temperature are related. Volume decreases pressure increases temperature increases Volume increases pressure decreases = temperature decreases 51. Identify where the following air masses are formed? cp ct mp mt Northern Canada Mexico Northern Pacific ocean or Atlantic ocean Gulf of Mexico, central Pacific Ocean 52. Identify parts of the weather symbol Temperature Current weather Dew Point 75, 1010 Ridley Park 62 Pressure Wind Direction City Name Wind speed
