Inert gas

physical law such as Boyle’s law states that P, the exerted fixed mass of gas at a constant temperature and V, the volume have a relationship. Their kind of relationship is V=f(P) relationship and it is believed that PV go together to remain constant. A water manometer is an instrument used to measure pressure. The model of kinetic theory of gases helps elaborate one of the most difficult…

Introduction A blender generally consists of a plastic or glass pitcher that locks into a large base. Some of blenders are made of stainless steel. The lid of the pitcher has a seal that prevents the food or liquid from splashing out while the blender is in motion. The motor has varying speeds that turn either two or four sharp, stainless steel blades. The blades slice, crush and blend the contents of the pitcher..Blender is a must have kitchen equipment for nearly all families today, especially…

Although they may be oddly shaped, volumetric and Erlenmeyer flasks are closed-end air columns, and they abide by the conventional rules of resonance. When a rubber stopper is inserted into a flask some air is forced out of the flask, and the stopper seals the flask so the air cannot get back in. This creates an area of low pressure within the flask. When the stopper is quickly pulled out of the flask, the air rushes back into the flask because the pressure of the atmosphere is higher than the…

Introduction Vapor pressure is the pressure of a vapor (gas) at equilibrium; equilibrium occurs when there is no net change between the amount of liquid and the amount of vapor because they balance each other. When the temperature of water becomes extremely low, as it does in this experiment, the rate of vaporization does not matter. The objective of this experiment is to determine the experimental heat of vaporization and compare it to the accepted heat of vaporization of water (40.7 kj/mol).…

sources at solid because it took time to sublime that solid and turn it into gaseous state for diffusion sources. The best efficient way is to use a gaseous diffusions sources. We got 2 candidates PH3 and POCl3. PH3 has a little quirk that escaping gas cannot be extinguished and exposure to fire may cause containers to rupture. This is a high temperature furnace which we will have a fire hazard so it would not wise to use PH¬3 in this. The best candidate will be POCl3 although it is an…

cause certain temperature changes based on the latitude of the incoming lights on to the earth 's surface. Radiation from the heat in the atmosphere helps the earth circulate air and water currents to regulate temperatures. The temperatures inside gas molecules create frictions when they are charged increasing the temperature. The energy of motion also known as Kinetic energy is what atoms have within the molecules that give them the ability to power up and move quickly, thus friction that heats…

In this figure (10°C trial), the two test tubes are clearly labeled with 1 and 7, test tube 1 contains the 1 cm³ liver and test tube 7 contains the 5 mL of hydrogen peroxide. these two test tubes are in a 250 mL beaker containing approximately 125 mL of tap water and ice. The thermometer was placed in test tube 7, which contains the hydrogen peroxide to measure the temperature of the solutions. The hydrogen peroxide was poured into the test tube containing to the liver and was observed.…

Gay-Lussac’s Law states that when volume is held constant, temperature and pressure are directly proportional. Gay-Lussac’s constant (G) can be defined as P=GTwhere pressure is in atm and temperature is in Kelvin. All three laws play a role in the ideal gas law, PV= nRT where P stands for…

The main purpose of this experiment is to purify an impure solid by the technique of recrystallization. This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent…

a) Heckel equation In 1961, Heckel proposed the most widely used equation describing pharmaceutical powder behavior in compaction. It was initially used to study the densification of ceramics and its correlation with pressure. It a first order process where powder pores elimination rate is correlated to the number of pores present. The rate of volume reduction increases as the number of pores decrease. Heckel equation relates the density, pressure and the pore fraction of the powder [16],.…
