2. A piston cylinder device initially contains 0.07m3 of nitrogen gas at 130KPa and 120oC. The nitrogen is now expanded polytropically to a state of 100KPa and 100oC. Determine the boundary work done during this process. 3. A refrigerator operates on the ideal vapor compression refrigeration cycle with R-134a as the working fluid between the pressure limits of

acetone is determined to be higher at higher temperature.This fits the theory where temperature affects the diffusion rate. Several recommendation should be taken during operating this experiment to minimize the errors. INTRODUCTION Mass transport in a gas or liquid generally involves the flow of fluid (e.g. convection currents) although atoms also diffuse. Solids on the other hand‚ can support shear stresses and hence do not flow except by diffusion involving the jumping of atoms on a fixed network of sites

Kinetic theory of gases Question: How does odor travel from one place to another? Kinetic theory of gases A gas is composed of atoms or molecules The gas particles are in constant random motion Kinetic energy is transferred between particles as they collide Pressure The force exerted per unit of area Formula: pressure/force area Measured by barometer A vacuum is empty space‚ with no particles or pressure. Atmospheric pressure is the collision air particles with objects Units of

"Graham’s Law"‚ which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. Graham was also the first to observe that palladium metal is able to absorb large amounts of hydrogen gas‚ especially at lower temperatures. He also observed that when the palladium with hydrogen dissolved in it is exposed to the atmosphere‚ then the metal is likely to become hot and suddenly discharge the gas. Graham found that colloids could be purified by placing them

Horse power vs. volt power (TS)Pollution‚ global warming‚ and the price of fuel pose real problems for an auto industry churning out gas vehicles‚ however‚ electric vehicles offer hope for the future. (PS)Most electric vehicles look and perform just like a gas vehicle.(SS) For example‚ the electric-powered Dodge Circuit EV resembles the gas-powered Dodge Challenger.(SS) Both sport the bold look of a muscle car‚ And both have all the standard features such as power windows and doors‚ gps‚ air conditioning

The following is the relation between the adsorption or gaseous adsorbent at definite temperature and the pressure of the gas is the first equation. n>1 Where x/m is the adsorption per gram of adsorbent which is obtained be dividing the amount of adsorbate (x) by the weight of the adsorbent (m). The pressure of the gas is p‚ k and n are constants. This relation is called as the freundlich adsorption isotherm. As see the following diagram. The value

Cutting operations should never be performed without a C) fire watch in the area. 11. Before performing oxy fuel cutting on a cleaned container‚ fill the container with an inert gas or C) water and position the container to displace as much air as possible from inside the container. 12. Because of its instability‚ the acetylene gas used in oxyfuel cutting must remain at pressures less than B) 15 psi when in its gaseous form. 13. Acetylene cylinders in use should be opened no more than C) 1-1/2 turns
