condense when they cool. In 1875‚ Raoul Picet used sulfur dioxide as a refrigerant and in 1931 Refrigerant R-12 was developed by Thomas Midgley and C. F. Kettering. The Kelvinator refrigeration unit‚ ice cream units‚ and Semi-hermetic compressors were introduced at the beginning of the 20th century. In this day and age‚ the refrigeration process hasn’t changed much‚ as it still uses the same refrigeration laws that have been around since the discovery of the “ice box”. Refrigeration

In this article I will explain whether I think gas prices will stay low. I have gathered some information and details to support my opinion. I will back up every detail that I think about whether gas prices should stay low. In the end I will have done explained why I think gas prices should stay low or not with some information to support it. I think that gas prices will not stay low. I think that gas prices will not stay low because their are alot of people who are taken advantages of it. People

4. To test ideal gas law Theory: Mariotte’s law Charles’ law Gay-Lussac’s law Ideal gas law Apparatus: beaker‚ boiling water‚ thermometer‚ pressure-meter‚ oil‚ closed tube. Procedure: 1) Set up all the apparatus 2) Open the rubber cap. Move the closed tube several times to ensure that the oil is spread equally. 3) Pour boiling water into the beaker and put thermometer into beaker. 1.

SINKHOLES Methane Gas Hydrates Scientists at Cardiff University have discovered the presence of large concentrations of methane gas trapped in the ocean floor. This gas is due to dying and decomposing sea organisms‚ or serpentinization. The sediment contains bacteria that produce methane‚ which accumulates as super concentrated methane ice‚ called gas hydrates. The layer of ice traps the methane gas‚ and scientists are studying it as a potential energy source. What is methane? Methane

Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

Gas Law Problems Boyles Law 1. A gas occupies 12.3 litres at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg? 2. If a gas at 25.0 °C occupies 3.60 litres at a pressure of 1.00 atm‚ what will be its volume at a pressure of 2.50 atm? 3. To what pressure must a gas be compressed in order to get into a 3.00 cubic foot tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure? 4. A gas occupies 1.56 L at 1.00 atm. What will be the volume

Experiment 3: Evaluation of Gas Constant Purpose: The purpose of this lab is to demonstrate the ideal gas law under ordinary conditions. In this lab‚ the variables in the ideal gas law are known or can be found aside from the constant R. Thus‚ the R values can be found and relatively determine the relevancy of the ideal gas law to the lab conditions. The ideal gas law was tested using the reaction: Mg (s) + 2HCl2 (aq) H2 (g) Procedure: 1. Ribbons of magnesium (5) were cut to the approximate

Arterial blood gases are only done in the very sick children‚ who have been intubated/ventilated and have arterial lines in situ (usually in the theatre prior to transfer to the PICU in Newcastle. Here is a stepwise approach to blood gas analysis. STEP 1: [pic] STEP 2: Look at pCO2 [pic] STEP 3: Look at Bicarbonate & Base excess (BE) [pic] Base excess (BE): Base excess is the amount mmol/l of base that is needed to correct pH back to normal when pCO2 is corrected
