decrease(temperature must be constant) CHARLE’S LAW acc to k.m.t the molecules of a gas posses kinetic energy which is directly proportional to temperature(at constant pressure) and when the temp is increased kinetic energy also increases due to which the sample of a gas expands in order to keep its pressure constant and volume increases AVOGADROES’S LAW acc to k.m.t when two gasses have same temperature their kinetic energy is same‚so they exert same pressure because molecules collide with same forcebut

the cars I made for my project will go. This illustrates how if the car doesn’t have enough kinetic energy the car won’t go very far. According to my research‚ If work‚ which transfers energy‚ is done on an object by applying a net force‚ the object speeds up and thereby gains kinetic energy(Kinetic Energy) which will make my car go further. This illustrates how if there is more potential energy than kinetic energy the car won’t go nearly as far as it could. According to my research‚ potential energy

chemical reactions using physical and chemical properties and balanced chemical equations. There are four different types of chemical reactions decomposition reactions‚ single displacement reactions‚ synthesis reactions‚ and double displacement reactions. A decomposition reaction happens when a compound breaks into two or more elements or compounds. Generally‚ for decomposition reactions heat‚ energy‚ light or electricity is needed to separate the compound. In a single displacement reaction‚ a single

SELECTED REDOX REACTIONS RESULTS AND DISCUSSION Oxidation-Reduction reaction also known as redox reaction is a process in which there’s a net movement of electrons between reacting species. These types of reactions involve two separate elementary reactions: one that loses electrons and another that gains the electrons that was lost. Gaining of electrons is referred to as Reduction reaction (the species that undergoes reduction is called as oxidizing agent) while losing of electrons is called

metals arranged in order of their reactivity based on displacement reactions‚ reduction of their oxides by hydrogen or carbon‚ the relative ease of decomposition of their compounds and reactions with oxygen‚ dilute acids and water. The higher up a metal is in the reactivity series‚ the more reactive it is. In the experiment conducted‚ the three metals‚ magnesium‚ zinc and copper each had to undergo displacement reactions and reactions with water‚ oxygen and dilute acids‚ to arrange them in the order

Chapter 14 - Kinetics of a Particle : Work and Energy In this chapter‚ students will get to learn about the concepts of involving work and energy including the work of a force that acts on particles. Therefore‚ students can develop the principle of work and energy and the concepts of a conservative force as this equation can be useful for solving problems involving force‚ velocity and displacement and also can solve the kinetic problems. So in general‚ this chapter will enable students to analyse

Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to the Collision Theory‚ during a reaction‚ particles

Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration
