Introduction

Temperature of the sun practical - Draft Results: Mass of plastic bag with water: 0.325kg �0.001 Area of plastic bag: 0.368m� �0.005 Initial temperature of water: 26�C �0.5 Time of water left under the sun (s) �0.5 Temperature of water (�C) ...read more.

Middle

Therefore, the experiment does not seem to be successful and the results obtained are inaccurate. Evaluation: Limitations Suggestions - The plastic bag is not stabilized on the ground; it leads to the spill of water. This will make the result inaccurate as the mass is changing - Use a container which allows the thermometer to be placed in the water ...read more.

Conclusion

This will lead to an inaccurate value of area of plastic bag - Use a fixed shape box to contain water which allows the area to be measured accurately - The black water is more concentrated at the bottom which may cause unequal absorption of heat by the water - Use a container which has a fixed shape and even surface ...read more.

  1. HL Physics Revision Notes

    The evacuated chamber consisted of two electrodes. One electrode was exposed to incident light. If the light was above the threshold frequency for the metal electrode, a current registered in the ammeter. The voltage was reversed so that the electrons causing the current would be repelled. The voltage that reduced the current to zero, also called the

  2. Researching water turbine designs.

    If the guide-vanes are fixed it is "single-regulated". Fixed runner blade Kaplan turbines are called propeller turbines. They are used when both flow and head remain practically constant, which is a characteristic that makes them unusual in small hydropower schemes.
