Myth (brief description)

There is an old wives tale that says, a watched pot never boils. Basically when you watch the pot supposedly it takes longer to boil than when your not watching it. But we are here to prove that wrong.

Here are my definitions:
Kinetic Energy: Amount of energy in particles depends on heat.
Solid: Firm, hard, or compact in substance.
Liquid: A substance that flows.
Gas: Any such combustible fluid used as fuel.
Molecule: Consisting of two or more atoms held together by chemical bonds.
Here are my questions:
Q1: What is the difference between a liquid and gas phase? A: The density of the liquid and gas.
Q2: What does it mean for a liquid to boil? A: Heat has to be applied to the liquid.

Q 3: No, because not all liquids have the same amount of kinetic energy, so if the liquid is cooler, it will take longer to boil, higher, shorter.
Q4:When it's liquid gets/is hot, the kinetic energy level is so high, that it can turn into a gas, then it'll have plenty of room to move. A liquid doesn't keep it's shape because it has a lot of room to move. When the liquid's temperature is cool, the molecules start to "pack in" and become a solid. The molecules of a solid don't have as much room to move, thus letting the solid keep it's shape until the temperature goes up.This all goes vice-versa also.
boiling point: the amount of energy required to turn a liquid to a gas
Q 6:The difference between the three waters is how pure they are.

Q5 :how do you determane when the liqucid boils if you arnt watching it? you have a camera watch it.
Q7 what happens if you change the kind of water will it have an affect on the amount of time the water takes to boil? in our experment we think that the time should change and the tempiture will also change.



Small Scale Test procedure

Variable Independent :Whether or not we watch the water
Variable dependent: How fast the water boils
Variable constent:Temp. of water pot, and stove, burner, water
Materials: 6,2 cups measurements if water, 1 pot, 1 stove, bottled water, well water, and city water.
Question: Will a watched pot of boiling water go faster if it is bottled city or well water?
hypothisis-- we think that it will not make a difference with the different types of water.
  1. Lay out materials.
  2. turn stove on.
  3. Measure out halfcup of water, different types of water.
  4. Pour water into pan.
  5. Get stopwatches ready.
  6. Put water on stove.
  7. Time how long it takes to boil water.
  8. Empty water from pan.
  9. Repeat steps.

Small Scale Test Conclusion

Claim: The bottled water boiled the fastest, versus the well and city water.
Evidence:the well water tolk the most time on average it was 2:59.68. the city water came in second at an average time was 2:51.721. bottled water came in last with a average time of 2:32.38.
Explanation: We think that the bottled water boiled the fastest because it has the least amount of molecules than city and well water. Also, if you pour another item in to the liquid, it can change the amount of kinetic energy in the liquid. We also think the well and city waters have more minerals. For example, if you put salt on an ice cube, then it will not need to be 32 degrees or higher for it to melt. The salt will make the kinetic energy in the ice cube higher.

Large Scale Procedure


Question: Will a watched pot of boiling water go faster if it is bottled city or well water?
Materials:6 2-cup measurments of well, city, and bottld water, 1 pot, and 1 stove
Hypothesis: If we watch a pot boil, then it will boil the same speed as a non-watched pot because watching it shouldn't affect the amount of molecules and kinetic energy in the water.
Variable Independent :Whether or not we watch the water
Variable Dependent: How fast the water boils
Variable Constant: Temp. of water pot, and stove, burner, water
Procedure:
1) Gather all of the materials listed above.
2) Turn on the burner you are using with your stove. Let it warmup for 2 minutes, unless you are using a gas stove.
3) Pour 2 cups of water in the pot.
4) Get the timer ready to time how long the water boils. Put the water on the stove.
5) When you are doing the "watching" trials, watch the pot until it boils. When you are doing the "non-watched" pot, listen until you hear the "bubbles" of the water popping.
6) After the water is done boiling and you recorded the data (time), you dump the water out of the pan. Let the pan cool off for about ten minutes or put it in the freezer for 2 to 3 minutes.
7) Repeat steps 3 through 4 until you've done 2 trials for watched and 2 trials for non-watched.
