Atmosphere & Air Quality
This gas makes up about 21% of the atmosphere and is necessary to support terrestrial life.
What is oxygen?
Pressure is defined as the force exerted per unit of this quantity.
What is area?
This law says pressure and volume are inversely related when temperature and amount of gas stay constant.
What is Boyle’s law?
At STP, one mole of any gas occupies this volume.
What is 22.4 L/mol?
A gas occupies 2.40 L at 100 kPa. It is compressed to 1.50 L at constant temperature. Find the final pressure.
What is 160 kPa?
Clue: This hazy form of air pollution is produced when vehicle and factory emissions react with sunlight.
What is photochemical smog?
This is the SI unit for pressure.
What is the pascal (Pa)?
This law says the pressure of a gas is directly proportional to temperature when volume and amount stay constant.
What is Gay-Lussac’s law?
At SATP, one mole of any gas occupies this volume.
What is 24.8 L/mol?
A gas in a rigid container has a pressure of 220.0 kPa at 300.0 K. It is heated to 360.0 K. Find the new pressure.
What is 264 kPa?
This component of smog can irritate the eyes and respiratory system when found
What is ground-level ozone?
Give the standard conditions for STP.
What are 0 °C and 101.325
This law combines Boyle’s law, Charles’ law, and Gay-Lussac’s law for a controlled amount of gas.
What is the combined gas law?
In a gas mixture, this term describes the pressure a gas would exert if it were the only gas present.
What is partial pressure?
A gas occupies 1.80 L at 95.0 kPa and 290 K. It is changed to 101.3 kPa and 273 K. Find the final volume.
What is 1.59 L?
Name both gaseous pollutants identified in the text as contributors to acid precipitation.
What are sulfur dioxide and nitrogen oxides?
Give the standard conditions for SATP.
What are 25 °C and 100 kPa?
This law says volume is directly proportional to the amount of gas when temperature and pressure remain constant.
What is Avogadro’s law?
When a gas is collected over water, the total pressure includes the gas plus the pressure of this substance.
What is water vapour?
How much volume would 2.50 mol of any gas occupy at STP?
What is 56.0 L?
This Canadian scale is designed to help people assess the health risk that air quality may pose.
What is the Air Quality Health Index (AQHI)?
Atmospheric gas density is greatest at this location.
What is sea level?
This law states that the total pressure of a mixture of non-reacting gases equals the sum of the partial pressures.
What is Dalton’s law of partial pressures?
The textbook contrasts this older index with AQHI by noting it reports the level of the worst individual pollutant rather than overall health risk.
What is the Air Quality Index (AQI)?
A gas mixture has a total pressure of 375 kPa. If oxygen’s partial pressure is 145 kPa, what is the partial pressure of nitrogen?
What is 230 kPa?
