Kinetic Art Kinetic art: the art of motion. Kinetic art contains a/or several moving parts and depends on motion for its effect. The motion of the art work can be provided in virtually any way. It can be powered by natures elements; wind‚ wave power from water‚ or heat from a fire; It can also be powered mechanically through electricity‚ steam‚ clockwork using earths natural phenomena’s ‚ gravity‚ motors‚ or even through the observer such as cranking a handle‚ or giving a push.

EXPERIMENT : - 2 EXPERIMENT Verification of Bernoulli’s Energy Equation THEORY For steady incompressible flow Bernoulli’s energy equation along a streamline is written as [pic] constant where [pic] = pressure‚ [pic] = velocity and [pic] = height from datum Purpose of this experiment is to verify this expression. In the special apparatus the pipe is tapered with the cross section decreasing in the direction of flow first and then

Another postulate of the kinetic molecular theory is that gas particles are always in motion‚ like the other states of matter. But they are different in that they undergo random translational movement. In solids‚ the particles mainly experience vibrational motion and in liquids they mainly vibrate and rotate‚ with some translational motion. Gas particles move rapidly in straight lines‚ unless acted upon by another particle or the walls of a container. This continuous contact with the container leads

The kinetic theory of gases describes a gas as a large number of small particles (atoms or molecules)‚ all of which are in constant‚ random motion. The rapidly moving particles constantly collide with each other and with the walls of the container. Kinetic theory explains macroscopic properties of gases‚ such as pressure‚ temperature‚ or volume‚ by considering their molecular composition and motion. Essentially‚ the theory posits that pressure is due not to static repulsion between molecules‚ as

higher average kinetic energy of molecules and more collisions per unit time. The rate of effective collision increases‚ the rate of reaction increases. As a result‚ the time taken for reaction decreases when temperature increasing. The graph shows that 1/T is decreasing when In 1/t is increasing. When the value of 1/T is bigger‚ the value of In 1/t will be smaller. In opposite situation‚ the value of 1/T smaller‚ the value of In 1/t will be bigger. Activation energy is the minimum energy is needed by

chemical reaction or a set of closely related chemical reactions. Enzymes do not affect the products of the reactions they catalyze‚ they only hastens the reaction process. Figure 1. Diagram showing the energy required on catalyzed and uncatalyzed reactions Enzymes technically lowers the energy of activation of the reactions thus increasing the rate at which the reactions take place (Fig. 1). Catalase is an enzyme capable of speeding up the breakdown of hydrogen peroxide into water and oxygen gas

The idea of kinetic art is getting a bit of a workout at the moment. MIT Museum recently hosted “year of kinetic art‚ including “5000 Moving Parts‚” a kinetic art exhibiton featuring large-scale works by Arthur Ganson‚ Anne Lilly‚ Rafael Lozano-Hemmer and John Douglas Powers. Plus the Kinetic Art Organization has published a digital “International Collection of Essays About Kinetic Art—2013—volume 1.” The two don’t overlap: The MIT show highlights a somewhat different segment of artists working

Title Experiment 17 Reaction Kinetics- Determination of the Activation Energy of the Reaction Between Oxalic Acid and Potassium Permanganate. Objective To determine the activation energy of the reaction between oxalic acid and potassium permanganate. Theory and Background Activation energy is the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport. In terms of the transition-state

Use the knowledge of kinetics to explain each of the following statements. a. An increase in temperature at which a reaction takes place causes an increase in reaction rate . An increase in temperature means increasing the energy of the molecules present. If the molecules has more energy ‚ then more of the them will collide often with enough energy ‚ to overcome the activation energy barrier. causing the reaction to proceed more quickly. b.An addition of the catalyst increases the rate at which
