“Torching Tiny Teddies” Energy Efficiency Experiment
Aim: To test the energy efficiency of a tiny teddy in kilojoules by burning the tiny teddy beneath a test tube of water. The water temperature is then measured to see how efficient the transformation of energy is. It is important to see how efficient the transformation is as it will give an indication to whether burning tiny teddies would be an efficient source of energy.
Hypothesis: It was hypothesised that the temperature would rise due to thermal energy being transformed via radiation. Also that the tiny teddy would not be an efficient source of energy as most of the energy would still be in the bear, and others would be lost through other forms such as heat ,light and sound energy.
Materials:
- 1 boss clamp
- 1 test tube
- 1 retort stand
- 1 heat mat
- 1 tiny teddy
- 1 thermometer
- 7mL of water
- 1 miniature stand
- 1 box of matches
Method:
1. All experimenters put on safety goggles, gloves and lab coats.
2. Set up retort stand on the heat mat, and attach the boss head clamp.
3. Fill test tube with 7mL water and place in the clamp
4. Record the mass of the teddy bear and the energy in the teddy bear (per 100g and in KJ)
5. Put teddy on the miniature stand, and adjust the boss head clamp so that the test tube is 1cm away from the tiny teddy
6. Measure the temperature of the water using the thermometer and record the results
7. Light the tiny teddy using matches until the bear is burning
8. Once the tiny teddy stops burning, record the temperature of the water using the thermometer (swirl the water so it evens out).
Calculations:
Using the temperature change we can calculate how much thermal energy was transferred into the water. The change in temperature was a difference of 14’C, from 26’C to 40’C. Therefore to rise 1mL of water by 14’C you need 58.16J.
( 14’C X 4.18J = 58.16J )
To rise 7mL of water by 14’C you need 407.12J, which creates the total energy that’s gone into

Abstract: The purpose of this experiment is to study the energy changes associated with the phase changes of water. In this experiment we know the water is gaining energy so we know the heat is going to be positive and we can use the equation MCΔT to find the energy change. The specific heat will be 1 and we just have to measure the water to find the mass and take the temperature before and after we start to find the energy change.…

A battery contains stored energy in the form of chemical energy. What are some examples of devices that are powered by batteries ___________________ _________________________________________________________________________ What different forms of energy are demonstrated by these devices ___________________ _________________________________________________________________________ Gizmo Warm-up Energy constantly changes from one form to another, but in a closed system, the total amount of energy always remains the same. This concept is known formally as the law of conservation of energy. The Energy Conversion in a System Gizmo allows you to observe the law of conservation of energy in action. In the Gizmo, a suspended cylinder has gravitational potential energy. When the cylinder is released, the gravitational potential energy is converted into kinetic energy, which causes the stirrer in the water to spin.

A coffee cup calorimeter is an apparatus that is used to measure the quantity of thermal energy gained or lost in a chemical reaction. This experiment utilizes this apparatus, which is made from two styrofoam cups with plastic lids and a thermometer, to measure changes in thermal energy of various reactions. When using this type of apparatus, it is assumed that no heat is transferred between the calorimeter and the surroundings, and that no heat is absorbed or released by the cup. This allows for determination of enthalpy change, which will then allow for the calculation of heat absorbed or released.…
