  • Carbon Dioxide Directly Proportional
    1,251 words
    ... le then existed he could not, and did not, determine the relationship between degree of hotness (temperature) and volume of a gas quantitatively. (Siebring, Richard, Page 32) Guillaume Amontons (d. 1705) developed the air thermometer, which uses the increase in the volume of a gas with temperature rather than the volume of a liquid. The air thermometer is an excellent demonstration of Charles' law because the atmosphere maintains a fixed downward pressure above a small mercury plug of consta...

  • Ball Bearings Cm

    SC 1: Investigating Terminal Velocity When an object falls through a fluid it accelerates until it reaches its terminal velocity. At this speed the forces acting on it are balanced. My task is to investigate the factors that affect the terminal velocity of a falling object. I am going to investigate how mass affects the terminal velocity. I think that as the mass of the ball bearing increases so does the weight of the ball bearing, which requires more friction to balance the ball bearing's weigh...

  • Concentration And Reaction Rate

    ... e light intensity the same throughout the entire experiment by working in the shade. Prediction: I predict that as concentration of thiosulphate increases so will reaction rate. Concentration of a reactant affects reaction rate because there are more frequent successful collisions. Assume a person has two chemicals x and y, which react when put together. If all input variables remained constant apart from concentration then fastest reaction rate possible would be to mix (assuming there isnt ...

  • Friction At The Atomic Scale
    1,010 words
    Friction at the atomic scale. From the article "Friction at the Atomic Scale" by Jacqueline Krim we learn that standard friction and friction at the atomic scale are quite different. In my summary paper I would like to try to explain that fact based on the article. Having used different apparatus, the scientists made an experiment to prove that physicists didnt pay enough attention to the study of frictions atomic level or nano tribology for a long time wrongly. However now it was determined tha...

  • Magnetic Field Generate Electricity
    2,438 words
    Planning Aim and hypotheses According to Flemings Rule, electricity is generated when movement occurs in the magnetic field. Alternatively, switching direction of the magnetic field also works. Alternating current is a good way of alternating the field direction. The electricity generated, of in the other words, the electromotive force, is measured in volts. By varying different parts of the apparatus, the EMF output could also vary. The aim of this investigation is to establish a connection bet...

    Physics Coursework: - Bridges. Plan. Aim: The aim of this experiment is to find out the amount of sag a bridge of different lengths can cause when under different kinds of tension and mass. Apparatus: To carry out this experiment we will need the following apparatus Weights (In different proportions) A measuring apparatus (Ruler) 1 metre of wood Two wooden blocks. Method: We will assemble the apparatus together and set the pieces up as shown in fig. 1. The two wooden blocks shall act as the supp...

    Explain what is meant by the term an economic model and outline a model of price and output determination in a free market. Examine the effect of a change in real disposable income on equilibrium price and output. An economic model or theory is a simplified explanation and analysis of economic behaviour. It allows us to predict, and therefore intervene, if we do not like the outcome of a possible chain of events. Theories and models are mainly derived from past responses to similar stimuli or fr...

    If Varying Currents Affects The Loss In If Varying Currents Affects The Loss In Mass At The Electrodes To find out how varying the current affects the loss in mass of the anode and the gain in mass in the cathode Introduction - Purifying Metals It has been found that when a copper solution is electrolyzed using copper electrodes, the anode looses mass and the cathode gains mass. This is an investigation into how varying the current affects the change in mass of the electrodes during electrolysis...

    Investigation Of Four Resistors Connected In Series Investigation Of Four Resistors Connected In Series And In Parallel. Investigation of four resistors connected in series and in parallel. Background: Resistance is what opposes the flow of electrons in an electric current through a conductor. Resistors are conductors that have a high resistance. A conductor is the material through which an electrical current flows. ? The Resistance, (R) of any conductor is given by the equation R = V/I? ? ? ? ?...

  • Measuring Cylinder Reaction Rate
    3,430 words
    How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+SO 2 + S 2 +H 2...
