inbetween convert this energy to another form, Efficieny- e.motor=85%, combustion= 20% Hydrogen is not a source of energy but a means of transportation Types of energy: kinetic e(in joules)= .5mv^2. Solar energy- 1gw per km^2 Solar energy can be turned into electricity through solar cells 15%=cheap, 40% efficiency=expensive. Caloric theory of heat=caloric fluid flows from hot object to cold.

Ball Experiment Name Institution Affiliation Bouncing Ball Experiment Introduction Aim: To use tennis balls to demonstrate that as the height of the drop increases, its velocity changes, depending on the type of material of the ball. Theory: Energy is required in varied phenomena. Light, sound, and movements are examples of tasks that require energy in order to perform. Energy is the capacity to undertake work, and the easiest way to measure it is through observation as it is converted

can be defined as the amount of reactants consumed or products formed in a unit of time (Laidler, 2018). The equation for this is (bbc.co.uk, 2014). When calculating clock reactions, there are a number of individual factors to consider. Chemical kinetics is

Abstract The “Chemical Kinetics” experiment was done to investigate the changes in the rate of reaction under the effect of concentration, temperature, and presence of a catalyst. It was determined that as the concentration of reactants and the temperature increases, the rate of the reaction increases as well. Also, the reaction was run by the presence of catalyst, and the rate of the reaction increased drastically in the presence of it. The order of the reaction with respect to each reactant

CHEMICAL KINETICS: IODINE-CLOCK REACTION DATE SUBMITTED: 14 DECEMBER 2012 DATE PERFORMED: 7 DECEMBER 2012 ABSTRACT Chemical kinetics involving reaction rates and mechanisms is an essential part of our daily life in the modern world. It helps us understand whether particular reactions are favorable and how to save time or prolong time during each reaction. Experiment demonstrated the how concentration, temperature and presence of a catalyst can change the rate of a reaction. 5 runs of dilution

If the height of the peak is not tall enough the coaster won’t enough potential energy and will subsequently not have enough kinetic energy or a large enough velocity. Causing the coaster to fall depending on the safety system used. All modern roller coaster have a system that the carts slot into so when it’s upside down it will hang if motionless rather than just fall as a back-up

hydropower, solar power, wind mills and nuclear power etc. There are two main types of energy that is kinetic energy and potential energy. If the object is at rest then the energy it possess is called potential energy and if the object is in motion then it possess kinetic energy. A well-known scientist called Gottfried Wilhelm Leibniz, formulated another theory of movement (flow) in view of kinetic energy and potential energy, which placed space as relative, though Newton was altogether persuaded that

calculated by using Rate of Reaction = Molestime of reaction Collision Theory : In order for atoms/molecules/ions to react, they must collide with each other, the rate of reaction is directly proportional to the collision frequency. The greater the number of collisions, the faster the reaction will take place. Activation Energy : For these collisions to take place and the reactions to happen, a minimum amount of kinetic energy must be possessed by the particles that are going to collide with

PLANNING Investigating the Kinetics of the reaction between Iodide ions and Peroxodisulphate (VI) ions By the use of an Iodine clock reaction I hope to obtain the length of time taken for Iodine ions (in potassium iodide) to react fully with Peroxodisulphate ions (in potassium Peroxodisulphate). I will do three sets of experiments changing first the concentration of iodide ions, then the concentration of Peroxodisulphate ions and finally the temperature of the solution in which the reaction

Investigating Enzyme Activity Aim: To investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) Variables: These factors could effect the rate of reaction on an enzyme: · pH · Concentration · Temperature · Surface Area pH - Enzymes function at different pH values. In neutral conditions the amount of oxygen gas given of in an enzyme-catalysed reaction will increase. An enzyme is
