ARE YOU A GOOD BOSS-OR A GREAT ONE 1. What are the pitfalls that plague managers? Ans. Many managers underestimate the transformational challenges of their roles. Managers in new assignments start out as receptive to change but as the managers start to settle in an organization they lose their fear of imminent failure and often grow complacent. Most bosses reach a level of proficiency and stop there-short of what they could and should have become‚ they stop growing and improving. Most often managers

he only chemical elements which are stable multi atom homonuclear molecules at standard temperature and pressure (STP)‚ are hydrogen (H2)‚ nitrogen (N2) and oxygen (O2); plus two halogens‚ fluorine (F2) and chlorine (Cl2). These gases‚ when grouped together with the monatomic noble gases; which are helium (He)‚ neon (Ne)‚ argon (Ar)‚ krypton (Kr)‚ xenon (Xe) and radon (Rn) ; are called "elemental gases". Alternatively they are sometimes known as "molecular gases" to distinguish them from molecules

Ideal Gas Behavior Author: VanessaStoll Lab Partners: Janelle Vallejo Instructor: Nieves Montano Chem 151‚ Section 002G Date Work Performed: February 12‚ 2014 Date Report Submitted: February 20‚ 2014 Abstract: This paper reports a lab experiment done on the ideal gas law to determine differences in gas based upon their “R” constant difference to 0.082057. A total of seven gases were tested‚ which included‚ Ethanol‚ Hexane‚ Cyclohexane‚ Pentane‚ Ethyl Acetate‚ Butane and Acetone

You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas. 1. Start Virtual ChemLab and select Boyle’s Law: Pressure and Volume from the list of assignments. The lab will open in the Gases laboratory. 2. Note that the balloon in the chamber is filled with 0.300 moles of an ideal gas (MW = 4 g/mol) at a temperature of 298 K‚ a pressure of 1.00 atm‚ and a volume of 7.336 L.

Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other‚ using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the density of the gas‚ under constant temperature and pressure. The significance of this experiment was that in led to a reevaluation of the concept of the movement of matter‚ realizing that diffusion dealt with small immeasurable elements

Lab: Gas Laws Purpose: Obtain a reference of temperatures effect on gas using Charles’ law when heating a capillary tube in water on a heated hot plate. Then‚ cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microLAB sensor and graphed using microLAB software. A final determination of experiments determined absolute zero versus actual absolute zero will be

Colligative properties in your Coke Have you ever put salt on snow to get rid of it‚ or wondered how your car engine stays warm in cold weather? If you have‚ you’ve probably noticed that the salt quickly melts the snow‚ and you’ve wondered how the engine can stay warm‚ when the metal on the outside of the car is cold. These are just some of the many examples of how colligative properties work in our everyday lives. A colligative property is a property of a solvent that depends on the amount

Cascade control is a powerful extension of conventional 3 Cascade control is a powerful extension of conventional 3-term feed term feed back - control control. It is a strategy which compensates for specific disturbances at source and largely Prevents them from affecting process being controlled. A cascade control scheme has two controllers‚ the output of the master controller being used to adjust the set point of the slave controller The effect of steam pressure disturbances can be compensated

ENGINE INSTRUMENT SYSTEMS I. Introduction A. Purpose – measure and indicate the operation of the engine B. Measuring (or sensing) and Indicating 1. Measuring – sending unit or sensor detect temperature‚ pressure‚ speed‚ etc. 2. Indicating – indicating unit or gauge displays data for the operator to use 3. Examples – engine instrument systems include: a. Tachometer – indication of engine crankshaft speed in Rpm b. Manifold absolute pressure (MAP) – indication of pressure in the induction system (intake
