Properties of gases can be described qualitatively and quantitatively, and can be predicted.
Air quality can be affected by human activities and technology.
People have a responsibility to protect the integrity of Earth's atmosphere.
Overall Expectations
F1. analyse the cumulative effects of human activities and technologies on air quality, and describe some Canadian initiatives to reduce air pollution, including ways to reduce their own carbon footprint;
F2. investigate gas laws that explain the behaviour of gases, and solve related problems;
F3. demonstrate an understanding of the laws that explain the behaviour or gases.
Specific Expectations
F1.1 analyse the effects of air quality on some technologies and human activities (e.g. smelting; driving gas-powered vehicles), including their own activities, and propose actions to reduce their carbon footprint
F2.1 use appropriate terminology related to gases and atmospheric chemistry
F2.2 determine, through inquiry, the quantitative and graphical relationships between the pressure, volume, and temperature of a gas
F2.3 solve quantitative problems by performing calculations based on Boyle’s law, Charles’s law, Gay-Lussac’s law, the combined gas law, Dalton’s law of partial pressures, and the ideal gas law
F2.4 use stoichiometry to solve problems related to chemical reactions involving gases (e.g., problems involving moles, number of atoms, number of molecules, mass, and volume)
F2.5 determine, through inquiry, the molar volume or molar mass of a gas produced by a chemical reaction
F3.2 describe the different states of matter, and explain their differences in terms of the forces between atoms, molecules, and ions
F3.3 use the kinetic molecular theory to explain the properties and behaviour of gases in terms of types and degrees of molecular motion
F3.4 describe, for an ideal gas, the quantitative relationships that exist between the variables of pressure, volume, temperature, and amount of substance
F3.5 explain Dalton’s law of partial pressures, Boyle’s law, Charles’s law, Gay-Lussac’s law, the combined gas law, and the ideal gas law
