Kinetic energy

highly influenced on the reaction rate, when the particle size of the catalyst was decreased, therefore their surface areas was increased and the ratio of catalyst surface and reactant volume was playing a crucial role for controlling the reaction kinetics. The reaction was takes place on the surface of a substance, increasing the surface area should increases the quantity of the substance that is available to react, and will thus increase the rate of the reaction as well. The size and shape of…

transfer of energy. However, nonphysical beings cannot influence transfer of energy. Here is the reasons. First, the transfer of energy occurs in space. Only one thing in space can transfer energy to another thing in space. Nonphysical beings don’t have spatial location, so they cannot involve the event of energy transformation. Second, Only a thing has energy can cause the transfer of energy. Because the physical universe is an energetically closed system. That is to say, the total amount of…

The hot and rapidly expanding gases are directed aft through the turbine rotor assembly. There thermal and kinetic energy are converted into mechanical energy. The gases are then directed out through the exhaust duct. Theoretical Cycle of GTE Let’s discuss a little on the cycle and theory of the gas turbine before we discussion on construction and design. As you are aware, a cycle…

Biology 10-19-15 Energy Transfer Energy transfer occurs in all cellular activities. For three of the following five processes involving energy transfer, explain how each functions in the cell and give an example. Explain how ATP is involved in each example. Adenosine Triphosphate, or ATP, is the most useful form of energy in the human body. Humans use it for everything from lifting a pin to running, to breathing. Converting energy from food to ATP takes a lot of energy and requires many…

Analysis/Discussion: This graph above shows that different heights does affect the speed of a shuttlecock. On the x axis, the data is the height of where the shuttlecock is dropped from, while the y axis is the average speed (m/s). The height where the shuttlecock is dropped increases, as the average speed of each height increases as well. The result of the graph is shown that the line keeps on increasing even if it is not a straight line graph. These results support my hypothesis, which states…

These reactions are concerted reactions that take place in a single step. This means that there are no intermediates or carbocations that are formed. In SN2 reactions, there are high energy transition states. An SN2 transition state has a planar arrangement of the carbon atom and the remaining groups. Also in this state bonds are either breaking or forming. During this state the molecule has a delta negative charge on the partially…

flourish. There is one more additional layer that is actually vertical and overlaps the exosphere, thermosphere ,mesosphere and the earth 's magnetic field that causes the gasses within this portion of the atmosphere to become highly excited by the energy emitted from the sun, charging its…

The Effect Of Temperature On The Rate Of Maggot Movement. Environmental Systems and Societies ---Planning Lab--- Gaurav Iyer Research Question To what extent does the temperature affect the movement of Maggots? Introduction The Experiment aims to analyze the behaviour of the maggots. In this case, behaviour is defined as the way organisms respond to their environment. In the experiment, the orientation of the movement of organisms and gametes in response…

Water a vital biological molecule Molecule of water Water is a substance which is transparent, odourless and colourless liquid that has a boiling temperature of 373K, freezing temperature of 273K meaning it is liquid at room temperature. Water is a compound containing 2 hydrogen atoms, but also has an oxygen molecule as well this means it has the molecular formula of H2O. The relative atomic mass of water is around 18 with “11.188% being hydrogen and 88.182% being oxygen” [1]. When bonded it…

The SEM produces a largely magnified image by using electrons instead of light to form an image. A beam of electrons is produced at the top of the microscope by an electron gun. It consists of an electron gun to produce high energy electron beam. A magnetic condensing lens is used to condense the electron beam and a scanning coil is arranged in-between magnetic condensing lens and the sample. The electron detector (Scintillator) is used to collect the secondary electrons and can be converted…
