Learning Objectives (in ? Form)

• Whats the difference between a chemical and
  physical change? How can you tell which change
  occurred?
• How are changes in matter related to changes in
  energy (endothermic vs. exothermic)?
• What are the 8 forms of energy related to changes

RULES

1. There will be round robin play and all questions
   will be all play except for the daily doubles.
2. The teams who answers correctly win the point
   value of the question.
3. If a team answers a daily double incorrectly,
   then that team will lose the number of points
   they bid, and any other team can ring in by
   raising their hand and answer at that point.
4. There are two daily doubles available.

Lets play

11
M, V, D for 100

• The measurement of the force of gravity acting
  on your body is called your ____________. How is
  this measurement of force different from mass?
• Weight- changes depending on the force of gravity
  at various locations

12
M, V, D for 200

• What would be your mass if you are 50 kg on
  Earth and you go to a planet with 5 times the
  gravity of Earth? What would your weight be if
  you are 110 lbs. on Earth and you to the same
  planet?
• Mass is still 50 kg
• Weight 110 x 5 550 lbs.

13
M, V, D for 300

• The amount of matter contained in a certain
  volume is called ___________. How can this be
  used to determine if an object will sink or float
  in water? Provide waters density in your
  answer.
• Density- more dense substances sink (more than 1
  g/mL) , less dense substances float (less than 1
  g/mL)

14

Substance Density (g/mL)
Water 1.0
Oak Wood 0.85
Lead 11.3
Platinum 21.5

• Suppose an object has a mass of 43 g and a
  volume of only 2 mL. What is the likely identity
  of the object?
• Platinum

15
M, V, D DAILY DOUBLE!!!

• Suppose you obtained a sample of oak wood and
  platinum both with a volume of 5 cm3. Which
  would have the greater mass? Explain your
  answer.
• Platinum- it has a higher density so if the
  volumes were equal, then the platinum sample have
  to have a greater mass.
