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

The testing for the Doll Test OR Eye Color Experiment resonated more with children is because children are brought up in discrimination house hold. Doll test told that how equal size the dolls were except for their color‚ to test children’s racial perceptions. Their subjects‚ where at least the children between the ages of three to seven‚ were asked to identify both the race of the dolls and which color doll they prefer. Eye Color Experiment talks about on how children treated each other by eye color

Smoking A Bad Habit There are lots of negative effects of smoking. Smoking has been proven to be very dangerous for health. As one cigarette contains more than 4000 chemical substances‚ therefore‚ it causes for many dangerous diseases such as heart attacks‚ asthma‚ bronchitis or lung cancer. According to a recent report in Britain close to 3‚500 people are killed each year in road accidents and 120‚000 are killed by smoking. Furthermore‚ smoking costs governments millions of dollars because of the

However‚ smokers do not fully understand the risks they take by smoking. It affects a person physically and mentally‚ economically and socially. First of all‚ smoking affects a smoker physically and mentally. Nicotine in cigarettes or cigars is a

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
