    #1 - 3y #1: Given a mass of 15.03 grams, a diameter of 2.56 cm,

    and a length of 8.96 cm, find the density of acylindrical candle.

    y # 2: If this candle was placed in a large container ofwater, would it sink to the bottom, float on the surface,or submerge to a depth in the water? Explain

    y #3: If the candle was melted into a liquid mixture andthe wick removed, would the mixture beheterogeneous or homogeneous? Explain your answer.

    # 4 6y #4: Describe how Lavoisier used a candle and water to

    determine the oxygen content of air.

    y #5: Suppose you found a candle to be radioactive. Iteven glows in the dark. What type of energy/particlescould possibly be given off by the candle? How often

    would these energy/particles be released?

    y #6: Hydrofluoric acid (HF aq) and the candle wax areused when working with glass. Explain how thesethree items are used in this artistic forum.

    # 7 - 9y #7: List the main elements that make up the candle

    wax. List the main compounds released when the

    candle burns.

    y #8: Describe how a thermometer, sample of water, aCoke can, and a candle can be used to determine the

    heat output of the candle.

    y #9: Describe how the wax travels up the wick to beburned in the flame.

    #10 - 12y #10: What would happen if you collected the melted wax

    after burning down the candle, added a new wick, andreformed it into a new candle. Would this candle burn

    again and again? Explain

    y #11: Describe how to calculate the burn-out time of acandle.

    y #12: As the candle burns it releases various types of energyas well as chemical compounds. Why is convection neededto allow the flame to continue burning? What happens tothis convection when the burning candle is placed in asealed container and dropped?

    #13 - 15y #13: Explain how the candle could be used to

    determine the period of a pendulum with a length of

    2.00 m.

    y #14: You toss the candle to a friend. Describe the arcthe candle follows during the toss. Draw a sample arc.

    y #15: Describe what happens to the candle when it isdropped vertically near the surface of the earth, bothin air and in a vacuum.

    #16 - 17y #16: Our candle is dropped out of a slow moving

    airplane. Describe the path the candle takes as it falls

    to the earth; with no air resistance, with normal airresistance, and with/without terminal velocities.

    y #17: Calculate the velocity of the rolling candle as it

    rolls down a ramp (0.200 m high ramp). Calculatehow far it would fly horizontally across the floor if theramp was on a table 1.35 m high.

    #18y #18: While it is obvious that the candle cannot burn

    when exposed to the vacuum of space, how would the

    candle itself behave in space is forced to travel fasterand faster (up to the speed of light)?
