Behavior of Gases Essay Sample

The intent of this experiment is to carry on different experiments that will exemplify the different gas Torahs. We will be given a list of equipment demand to execute the experiment every bit good as general regulations to assist us make the experiment. We will look into three belongingss of gases force per unit area. temperature. and volume. By making this experiment we will be able to specify the gas Torahs. Harmonizing to Boyles. it states that a fixed sum of ideal gas that is kept at a fixed temperature. that the force per unit area and volume are inversely relative. if the temperature stays unchanged. Harmonizing to Charless Law. if the force per unit area of a gas is held changeless. as the gas is heated. its volume will increase and that chilling the gas will do the volume to diminish. Charles jurisprudence describes that of the Gay- Lussacs jurisprudence. who had really referenced unpublished work of Charles. The jurisprudence states that at a changeless force per unit area. the volume of the given mass of the ideal gas will increase/ lessening. the same ways as the temperature will increase/ lessening. An easier manner to construe this is that at a changeless force per unit area. volume and temperature are straight relative. Materials Lab quest Vernier gas force per unit area detector Temperature probe 20 milliliter gas syringe 125 milliliter Erlenmeyer flask 3 600mL beakers hot home base Dry ice gum elastic stopper with 2-way valve Procedure and observations ( Part 1 ) The first thing we did in this experiment was step force per unit area and volume.

To make this we used the lab pursuit and syringe. You attach the syringe to the valve of the gas force per unit area detector. We pick a volume and when reading the volume on the syringe make certain you read from the inside black ring on the Piston of the syringe. Make certain to link the gas force per unit area detector to the Lab Quest and take new from the file bill of fare. Then you will put up the informations aggregation. first alteration the aggregation manner to events with entry. so enter volume and units ( milliliter ) and choice Oklahoma. When roll uping the informations allow for the force per unit area to fluctuate and when it is stabilized. choice support and shop the information points. We will be roll uping five informations points. When you are forcing the syringe you are diminishing the volume. and when you pull you are increasing the volume. When you have finished roll uping the informations make certain you save it that manner you can see a graph of force per unit area vs. volume. ( Part 2 ) in this experiment we will be looking at the relationship between temperature and force per unit area. We will be taking the Erlenmeyer flask with the H2O and take the temperature of it. We will be seting the Erlenmeyer flask on a hot home base and merely raise or take down the temp to see how much force per unit area will exercise from the different temperature alterations. You will link the temperature investigation to impart 2 of the lab quest. take new from the file bill of fare. Change the graph scenes so that it shows force per unit area vs. temperature. and alter units to K ( Kelvin temperature ) .

When you start roll uping the information. you will take maintain to roll up the force per unit area and temperature informations. You will roll up the force per unit area at different temperatures. when you have completed roll uping five informations points. do certain to salvage your informations. ( Part 3 ) We so measured force per unit area and temperature with different per centums of anti freezing and ethyl alcohol. As you can see from the computations that none of them when multiplied together equal each other. In this tabular array Im non certain whether we didnt step it right or what precisely happened. but in notice as the volume decreased that the force per unit area increased and Im confused on whether that was supposed to be reversed. I feel this graph was besides a small off as you can see the best tantrum line merely goes through two of the information points. I dont cognize once more if possibly we measured incorrect but the force per unit area and temperature seemed reasonably changeless to me. Here is the tabular array below to demo the ethyl alcohol. anti freezing. force per unit area and volume

. I truly didnt understand if the Y 262x ( -265. 18 ) was supposed to be used or we were supposed to utilize our ain with our graphs. But I found my points confounding because in my volume vs. force per unit area graph. as the volume got bigger the force per unit area decreased. I dont cognize if this had to make with the issues we had with the lab pursuit because for my group it did take rather awhile to acquire points for the volume vs. force per unit area graph. Although my temperature vs. force per unit area graph seemed accurate because as the temperature increased the force per unit area increased. I didnt happen the absolute nothing merely because I was confused on whether to utilize the equation we were given or happen
