Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

Ball Mill Ball mill is the vital equipment for regrinding after primary crushing. It is extensively applied in cement‚ silicate products‚ new construction material‚ refractory material‚ chemical fertilizer‚ ferrous and non-ferrous metals beneficiation and glass ceramics industries. It is great choice for dry or wet grinding any kinds of minerals and other grindability materials. Ball mill is a widely used ultra-fine grinding mill in industrial production. Ball mill has a variety of types‚ according

Finding the Acceleration of a Ball Problem Statement: How does the height of a ramp that is comprised of two parallel rulers affect the speed of a steel ball bearing rolling down it? Hypothesis: If the steepness of the ramp based on the amount of books propping it up are increased‚ then the steel ball bearings’ speed will increase. Materials: 2 wooden meter sticks 1 steel ball bearing 5 workbooks A roll of masking tape A stopwatch A smooth‚ long surface (preferably a table) Procedures: Arrange

before and after the ball in the P.E.E/C.C.C format: Leila the protagonist and the main character of the story "Her First Ball" is described as a girl who lives in an area that is quite isolated from the excitement of the city. In fact‚ she even says that her closest neighbor lives 15 miles away. This is why this event‚ her first ball‚ is such a rare and an exciting occasion for a girl like her. In this essay I will be explaining how her thoughts and feelings before and after the ball changes. Before
