SCIENCE 7HEAT Test Review QuestionsMr. Birt

  1. Science Inquiry (Use the Science Inquiry booklet, the booklet review (p.23), and quizzes)

1)Define each of the following terms:

testable question, variable, independent variable, dependent variable, hypothesis, fair test, controlled variable, observations, conclusion

2)Given an example of a testable question

  1. What are the independent and dependent variables?
  2. State an hypothesis based on the testable question?
  3. Give an hypothesis using the independent and dependent variables?

3)For each of your labs: Paper Drop, Effects of Heat Demo, Heat versus Temperature Demo

– be able to give

  1. the independent and dependent variables,
  2. two controlled variables (except the Effects of Heat Demo) and
  3. the hypothesis.
  1. Thermometers

1)Celsius – What are the units (degrees) and scale basis (properties of water – boiling point, freezing point)?

- Also know the average normal body temperature and average room temperature

2)Liquid (Lab) Thermometer

- What are the main parts (label diagram)? Also the handout questions.

3)3 Types - Liquid Thermometer, Thermostat, Thermocouple (Notes and Comparison Table)

*What is its main use, main component, how it works, etc.?

  1. Effects of Heat

1)Demo - Know the 3 demos for the 3 states of matter (notes table) as proof for the effects of heat

2)Effects of heat applications – Know and explain at least 2 applications of effects of heat -use PTM

  1. Particle Theory of Matter(PTM)–

1)What are the 5 Main Points (Fill in the blank questions)?

2)3 States of Matter

  1. What are the 3 states of matter?
  2. Use a diagram to compare them based on the distance between the particles in each.
  3. What does each state do in container (in relation to the shape of the container)?
  1. Changes of state(Triangle and Table)

-What are the scientific terms and their definitions for the six changes of state?

1)Temperature, Heat, and PTM “QUIZ” –Know questions and table

2)LAB: Change of State – Know the IV, DV, and CVs

-Be able to graph temperature over time (title, and labels, units, scale for each axis)

3)Heating and Cooling Curves – Know basic features, be able to draw and read

-Identify states of matter and plateaus, know hidden heat and explain with PTM

-Know relationship between Boiling Point and Condensation Point, Freezing Point and Melting Point

  1. Boiling and Melting Points

1)Notes – BP/MP as properties

  1. Heat versus Temperature

1)Notes - What is the difference between heat and temperature (definitions and PTM), what is energy?

2)Heat Energy –

  1. Use the PTM to explain the effects of heating two different amounts of water.
  2. Given two different amounts of water, use the PTM to explain which has more energy.
  3. Be able to graph the change in temperature of a substance over time (given the title, the labels, units and scale for each axis)
  1. Methods of Thermal Energy Transfer

1)What is radiation and give examples, how is it prevented

2)What is thermal conduction, explain using PTM diagram, what states of matter does it occur in, give 2 good heat conductors, how is it prevented

3)What is convection, explain convection current using PTM diagram, what states of matter does it occur in, how is it prevented

  1. Energy

1)What is the difference between kinetic and potential energy (use a diagram)

2)Name 3 forms of energy that can be transformed into heat energy
