The study of gases has been a long concern of physical chemists: in fact, much of our knowledge of atomic structure and our calculations in quantitative chemistry have their roots in classic experiments on gases. These experiments will be explored, along with the mathematical formulae that they helped us to derive. Having acquired a strong understanding of the concept of molar ratios, students will use these calculations to solve a variety of problems involving the gaseous state. In this unit, students will also be introduced to the concepts of pressure and kinetic molecular theory. Technological and environmental considerations will be studied through guided independent work.

By the end of this unit, students should be able to

• • Explain that particles of gases are in constant random motion. (F2)

  • Understand the relationships between gas pressure, temperature, volume, and moles.(F2)

  • Calculate the final values for volume, pressure, temperature, or moles of a gas sample based on a given set of data.(F2)

  • Predict the spatial distribution, interaction, and motion of particles in a gas sample as variables are changed.(F2)

  • Interpret trends in data by examining the graph associated with each of the gas laws. (F1/2)

  • Compare the density of gases based on their behavior.(F3)

  • Use simulations to better understand the behavior of gases.(F3)

  • Understand how pressure, temperature, volume, and molecular weight affect how particles in a gas behave.(F2)

  • Apply the concepts of gas laws to stoichiometry problems.(F3)

  • Carry out stoichiometry problems with solid, aqueous, and gaseous states. (F3)
