Integrated Science

• The blanket of gas that surrounds the

  entire planet and extend to the edge

  of space.

  Our Atmosphere
• occupy far more space than the

  liquids or solids from which they

  form

  Gas
• The space occupied by the gas.

  Volume
• The force exerted by a gas against the walls of the container.

  Pressure
• The measure of the average kinetic

  energy of the particles in an object.

  Temperature
• The quantity of Gas.

  Amount of Gas
• It states that the pressure exerted by a gas (of a

  given mass, kept at a constant temperature) is

  inversely proportional to the volume occupied by it.

  Boyle's Law
• P ∝1/V - What Relationship?

  Inverse Relationship
• k = what?

  Proportionality Constant
• A gas has a volume of 3.0 L at 2.0 atm. What will

  be its volume if the pressure increases to 4.0 atm?

  1.5L
• It states that the volume occupied by a fixed amount

  of gas is directly proportional to its absolute

  temperature if the pressure remains constant.

  Charles's Law
• V ∝ T - What Relationship is this?

  Direct Relationship
• A gas has a volume of 3.00 L at 127C. What will

  be its volume if the temperature increases to 227C?

  3.75L
• It states that at constant volume, the pressure of a

  fixed amount of gas is directly proportional to the

  Kelvin temperature.

  Gay-Lussac's Law
• P1/T1=P2/T2 - What equation is this?

  Gay-Lussac's Law
• A gas has a pressure of 2.0 atm at 27.0C. What

  What will its pressure be if the temperature increases to 72.0C?

  2.3atm
• 0.00011% in the Atmosphere

  Krypton
• 0.00015% in the Atmosphere

  Methane
• 0.00052% in the Atmosphere

  Helium
• 0.00182% in the Atmosphere


  Neon
• 0.037% in the Atmosphere

  Carbon Dioxide
• 0.934 in the Atmosphere

  Argon
• 21% in the Atmosphere

  Oxygen
• 78% in the Atmosphere

  Nitrogen
• Source of all clouds and precipitation.

  Water Vapor
• Practically none up to about 4 percent by volume Gas

  Water Vapor
• Large quantity of solid and liquid particles suspended

  in air

  Aerosols
• Two Sources of Aerosols

  Natural Sources & Man-Made Sources
• What is this?

  Act as surfaces on which water

  vapor can condense

  Can absorb, reflect and scatter

  incoming solar radiation

  Contribute to the varied hues of

  red and orange at sunrise and

  sunset

  Aerosols
• Ozone

  form of oxygen that combines

  three oxygen atoms into each molecule
• Ozone Depletion

  UV energy removes chlorine atom from CFC Molecule
• What is the full meaning of CFC

  Chlorofluorocarbon
• Is 50 km up from the ground a good ozone layer?

  Yes
• Why is 20 km ozone bad?

  It acts as a greenhouse gas
• Radiosonde

  Used for looking throughout layers of the Atmosphere
• "Tropo" meaning

  "turn over" in the language Greek
• Troposphere height above sea level

  8 km to 14 km
• Most Dense layer in the atmosphere

  Troposphere
• Most of the clouds are here

  Troposphere
• Weather Phenomena mostly happens here
