Chapter 10 Test Review Presentation Transcript

  • 1. Chapter 10 Test Review
  • 2. Chapter 10 Test Review
    Bring a calculator and writing utensil to class.
    You must be able to operate the calculator that you bring for the test.
    A periodic table will be provided.
  • 3. Chapter 10 Test Review
    Many of the types of questions will be similar to the examples given in-class, in notes and handouts, and on homework assignments.
    The chapter 10 test will have all types of questions:
    multiple choice
    fill in the blank
    definition of terms
    short answer
    calculations (temperature conversions; q = mCp∆T; ∆H)
  • 4. Chapter 10 Test Review
    Terms that you should be able to define include: energy, kinetic energy, potential energy, law of conservation of energy, exothermic process, endothermic process, temperature, heat, convection, conduction, and radiation.
  • 5. Chapter 10 Test Review
    You must be able to convert temperatures from one scale to another.
    The following mathematical formulas will be given:
    K = ˚C + 273
    ˚F = 9/5˚C + 32
    ˚C = 5/9(˚F – 32)
    You must be able to use algebra to manipulate any of the above equations to solve for unknown temperatures.
  • 6. Chapter 10 Test Review
    The first set of calculations include heat transfer events and the equation q = m Cp ∆T. This equation will be given. You must know what each variable represents and what units quantities must be in when substituting into this equation.
    You must know ∆T = Tf – Ti.
    A table of specific heat values / Cp will be provided.
    You must be able to calculate unknown amounts of heat energy gained / lost in units of joules or kilojoules, values of specific heat, temperature change, or mass.
    You must know that 1 kJ = 1000 J.
  • 7. Chapter 10 Test Review
    The second set of calculations include calculations that relate to heats of reaction and enthalpy - ∆H.
    You must be able to identify if a reaction is endothermic / exothermic from given values of ∆H.
    You must be able to calculate the amount of heat energy, in kilojoules, absorbed / released in a chemical change starting from moles of reactant/product and grams of reactant/product.
    You must know 1 kJ = 1000 J.
