Experiment 5: Friction Laboratory Report Charles Sanchez‚ Geminesse Sianghio‚ Ferguie Solis Department of Chemistry College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract In this experiment‚ a block of wood is used to observe friction on different surfaces such that an extra weight is also added to the block of wood to measure the same units under the different surfaces. With also the use of lubircant a member of the group was asked to observe the

number 2 with power outputs of 239.4 W and 266.0 W when going up and down respectively. On the second activity‚ the graphs of the potential energy vs. time‚ kinetic energy vs. time‚ and mechanical energy vs. time of a ball thrown vertically were all predicted. Finally‚ the ball was tossed on the motion detector and the graphs of potential‚ kinetic‚ and mechanical energies vs. time were all produced using the Logger Pro. Introduction Work is said to be an act of exerting force. Whatever it is that can

think of. But‚ here is some more info on the Web shooter. First‚ the "works" of the Web shooter. The Web shooter has a heating coil in it. The heating coil is used for burning acetone. When the pressure valve is opened‚ it releases the pressurized web fluid. Which then goes through the heating coil. While this happens‚ the acetone will burn off and let the chemicals bond into a fiber. Now you’re probably wondering how does it shoot out? It gets out from...GAS PROPULSION. Now can you guess which gas?

Organic Lab 1: Fractional Distillation Discussion: With the purpose of the experiment being to identify the 30 mL of unknown liquid‚ the theoretical basis of simple and fractional distillation must be deconstructed and applied to the data obtained describing the liquid in question. Simple distillation is a separation technique which can be used to separate and purify distillates from a liquid mixture which ideally contains one volatile and one non-volatile compound. If such ideal conditions are

nematocidal activities. Due to its poor solubility there is a need to formulate this curcumin for better bioavailability. Curcumin was extracted by acetone using soxhlet apparatus and evaporated by means of vacuum rotary evaporator. The presence of curcumin was confirmed by differential scanning calorimetry. Nanosuspension was prepared by bottom up method using acetone and water solvent system. Stabilizers were added under optimized conditions in order to achieve suitable quality of nanosuspension. Then it

Heat‚ Kinetic Energy and Temperature SCI 110 02/01/2013 The study of heat relate to Kinetic theory of matter is that universe is made up of matter and energy. Matter is made up of atoms and molecules. Atoms and molecules are always in motion because energy. Energy forces them to contact into each other or vibrate back and forth. When this happens molecules and atoms
