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

1. Dancing Raisins Here’s another quick and easy science experiment. All you need is a glass of clear soda‚ such as ginger ale or club soda‚ and several small raisins. Fill a glass with soda. Leave about ½ inch (12.5 mm) of space at the top. Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons

The Manland Experiment 1. The Manland experiment lasted only one weekend in one store. The marketing advantages and disadvantages of expanding it to other stores? Do you think IKEA should do more with this idea? Why or why not? The advantage was this was an attempt to continue IKEA’s image as family-friendly with the goal to appeal to all men as an environment offering a rewarding shopping experience. The area was set up for men to play video games or watch sports while their wives or girlfriends

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

Once achieved‚ dip the nichrome wire in concentrated hydrochloric acid‚ and then dip it into a small amount of the unknown solid (or solution) to carry out the flame test. 5. Place the wire at the hottest part of a non-luminous Bunsen flame and record the observed colour of the flame.
