Gas Laws Gases exhibit many qualities that are very different from those of liquids or solids. Gases have particles that are farther apart when compared to liquids and solids. The particles in gases move at different speeds in random directions and they are constantly moving. These particles collide with each other and with whatever container or area they are in. Gases are also very easy to compress. They expand to fill their containers and they occupy far more space than the liquids and solids

surveys‚ weather studies‚ gas analyses and research of the atmospheres of other planets. They are usually made of glass or plastic‚ and while most are scored for measurement‚ some can measure changes digitally. The single-tube manometer measures only the pressure of a liquid‚ since there is no alternate place to compare gases. A U-shaped manometer essentially pits two different gas pressures against one another‚ and measures the strength of the captured gas. The free-flowing gas is usually air at the

English 1020 February 28‚ 2011 Diving into a Wreck In this poem‚ the author‚ Adrienne Rich‚ gives metaphorically details on an interesting‚ underwater adventure. The poem “Diving into a Wreck‚” is like reading a documentary on a person exploring into the ocean on search for a sunken ship‚ except Adrienne puts a personal meaning into every part of the poem. The wreck and the ocean give Rich a chance to talk about all kinds of other subjects. The title‚ "Diving into the Wreck‚" lays out the basic

Who is it that decides our fate‚ stating/deciding whether or not it’s worth being sustained? Euthanasia is a very controversial topic that is constantly being debated by many politicians. Some of these politicians have formed groups opposing the legalization of euthanasia. These politicians’ main argument is over the immorality of it‚ but still

of the Gas Law Constant Objectives In this experiment‚ we will determine the Ideal Gas Constant‚ R‚ which relates the number of moles of gas present to its volume‚ pressure and absolute temperature. Background To see how "R" was derived‚ we must look at the proportionalities defined by the other fundamental gas laws. For example‚ Charles’ Law showed us that the volume of a gas sample is proportional to its absolute temperature at constant pressure. Thus V ∝ T abs . In addition‚ Boyle’s Law states

Vanessa Gale Formal Lab: Evaluation of the Gas Law Constant Dr. Monzyk Due 06/25/2012 Purpose: The purpose of this lab is to evaluate the gas law constant. The ideal gas law is represented as PV=nRT‚ where R represents the gas law constant. To determine R‚ we must find the other parameters‚ P‚ V‚ n and T through the experiment. Equipment and Materials: Large beaker Ring stand Clamp Copper wire 100 mL eudiometer tube Magnesium (Mg) ribbon M6 H2SO4 (Sulfuric Acid) Wash bottle
