12. The particles of an ideal gas are assumed to be _________________________ , that is, particles that have a mass but occupy no volume. 13. Although gas temperatures are often measured with thermometers that report temperatures in _________________________ scientists generally use _________________________ temperatures for calculations.

3 14. The observation that the pressure of an ideal gas is inversely proportional to the volume it occupies if the _________________________ and the temperature are constant is a statement of Boyle’s Law. 15. For an ideal gas, volume and temperature described in kelvins are _________________________ proportional if the number of gas particles and pressure are constant. This is a statement of Charles’ Law. 16. It is always a good idea to include the units in a solved equation as well as the numbers. If the units cancel to yield a reasonable unit for the unknown property, you can feel confident that you picked the _________________________ , that you did the _________________________ correctly to solve for your unknown, and that you have made the _________________________ . 17. There are three different ways to convert between a measurable property and moles in equation stoichiometry problems. For pure liquids and solids, we can convert between mass and moles, using the _________________________ as a conversion factor. For solutions, _________________________ provides a conversion factor that enables us to convert between moles of solute and volume of solution. 18. Particles of matter tend to become more _________________________ (spread out). 19. Because there are more possible arrangements for gas particles when they are dispersed throughout a container than when they are concentrated in one corner of it, _________________________ suggests that they will spread out to fill the total volume available to them. 20. If less than 1 gram of the substance will dissolve in 100 milliliters (or 100 g) of solvent, the substance is considered _________________________ . 21. Nonpolar substances are _________________________ likely to dissolve to a significant degree in polar solvents. 22. If we need to predict the relative water solubility of two similar molecules, we can expect the one with the proportionally _________________________ polar portion to have higher water solubility.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
