moles of gas produced. Where P is the pressure in atm‚ V is the volume in Liters‚ n is the number of moles‚ R is the constant 0.0821(atm*L/K*mok)‚ and T is the temperature in Kelvins. In this lab the volume of reaction space needs to be measured. I have chosen to use Magnesium and the amount of H2 gas that the amount of magnesium‚ (.04g)‚ used is 0.00229 mol H2. Procedure 1. Fill a 125 mL flask with 50 mL of HCl (aq) 2. Obtain and set up the pressure sensor 3. Record intial temperature‚(
Premium Ideal gas law Pressure Gas
Conclusion: Boyle’s law states that for a fixed amount a gas at a fixed temperature volume is opposite to its pressure. The air in the marshmallow is what follows Boyle’s law. The marshmallow is similar to a gas because when the pressure in the syringe is decreased the pressure in the marshmallow is increased. The volume increases in the marshmallow. So basically when the plunger is pulled out the pressure in the syringe decreases and the volume of the marshmallow

stereotypes about each one of them began to pour out from each one of them. None of them had known each other previously‚ but they all had a stereotype tagged to one another. As they fought‚ they began to realize that the struggles‚ insecurities and pressures they had were the same ones that the people who seemed so different had. They touched on the lack of communication they all had with their parents. Their home life was not satisfying to them. This is very relatable to the viewer because everyone

used on a textured surface‚ such as carpet‚ and is pushed over the surface‚ sucking up dust and dirt as it goes. The suction is created by an air pump‚ a partial vacuum; it creates a difference in pressure between the inside of the machine and the outside air and dirt and dust is taken in to the lower pressure zone. Friction on the carpet causes the dust to be removed from the carpet‚ or other surface. Table of Contents 1. History and developments - Ives W. McGaffey -Hubert Cecil Booth -James

I. Introduction Pressure is the application of force to a surface ‚ and the concentration of that force in a given area . A finger can be pressed against a wall without making any lasting impression ; however ‚ the same finger pushing a Thumbtack can easily damage the wall ‚ even though the force applied is the same ‚ because the point concentrates that force into a smaller area. Volume is the quantity of three-dimensional space occupied
