Test 1- Review Sheet In addition to this review sheet, please review the content located under the “Weather Unit” tab of my website. Properties of Matter: Mass, Volume, Density The space that matter takes up is called? What are the units associated with this measurement? Volume- liters (milliliters, centiliters, kiloliters, etc.) The amount of matter in a substance is called? What are the units associated with this measurement? Mass- grams (milligrams, kilograms, centigrams, etc.) The amount of matter in a given space is called? Density (mass/volume) What is the difference between mass and weight? Mass- the amount of matter in an object Weight- gravitational pull on an object What is a measure of the average kinetic energy of molecules? What are the units associated with this measurement? Temperature- degrees celsius (°C) or kelvin (K) Behavior of Gases: Fill in the blanks Law: Variable 1: Variable 2: Boyle’s Law Pressure ↑ Volume Charles’ Law Temperature Volume Pressure-Temperature Law Pressure ↓ Temperature ↓ Suppose the picture below represented an experiment. What is the… Independent variable? Pressure (more weights= more pressure) Dependent variable? Volume (The amount of space the gas molecules takes up) Darker surfaces are warmer because they ___absorb___ radiation which cause particles to vibrate faster (kinetic energy is increased). Lighter surfaces are cooler because they ____reflect____ radiation. Electromagnetic Spectrum: Which part of the EM spectrum can be seen by the unaided eye? visible light Which part of the EM spectrum is felt as heat? infrared What is the relationship between frequency and wavelength? ↑ frequency = ↑ energy = ↓ wavelength (the opposite is also true) The bending of light that passes through a prism is referred to as __refraction__. Identify the types of heat transfer: Direct contact: Conduction Through electromagnetic waves: rays sunlight, light bulbs, camp fire Warm fluids (gas or liquid) rising , cool fluids falling: Convection Earth’s Atmosphere Which layer of the atmosphere does weather occur? troposphere Why does temperature increase in the stratosphere? Ozone is formed in this layer due to absorption of UV radiation. When ozone forms, heat is released which causes temperature to increase. How does pressure change with altitude? As altitude increase (you climb higher) pressure decrease (fewer molecules pushing down on you) Weather Describe/illustrate the movement of air in a low pressure systems. Warm air associated with low pressure systems will rise and rotate counter clockwise. Why do clouds form over low pressure systems? As the warm air rises in a low pressure system, the water vapor in the air will condense due to the lower temperatures in the upper atmosphere. Then water vapor condenses, clouds can form is dust particles are present. Describe/illustrate the movement of air in a high pressure systems. Cold air associated with high pressure systems will fall and rotate clockwise. Describe/illustrate what happens when a warm air mass comes in contact with a cold air mass. Why does this happen? Warm air will rise above the cold air mass because it is less dense (molecules are farther apart- not as closely packed). When this happens, clouds will form, precipitation may fall because of condensation that occurs as a result of lower temperatures in the upper atmosphere. What causes local surface winds? Differences in pressure caused by unequal heating of the Earth’s surfaces. List the conditions necessary for a hurricane to form. High humidity (lots of water vapor) A depression (such as a thunderstorm) Warm sea surface temperatures (at least 26.5°C or 80°F)
