The molar heat of vaporization of n-heptane for the rising T and falling T sets of data was 26.10 kJ/mol . This is the energy required to transform a given amount of n-heptane from a liquid into a gas at a certain pressure. In both table 1 and 2, the vapor pressure was gradually increased as the temperature increased. Also, the vapor pressure was decreased as the temperature decreased. This means that the data values that obtained from this experiment were true values. The isoteniscope method…

chemistry other units that are equivalent are atoms, formula units, and molecules. Gas Laws 3.How is the combined gas law used to calculate differences in pressure, temperature and/or volume for a fixed amount of gas? This is a combination of three different gas laws that give variables for pressure, temperature, and volume that can find the amount of a…

If a compound is an electrolyte it conducts electricity by breaking down into ions when dissolved into a solution. A non-electrolyte compound does not dissociate in solution. A non-electrolyte compound cannot conduct electricity because it dissolves in solution as molecules instead of ions. Colligative properties are properties of a solution that depend on the amount of solute dissolved, and not dependent on the identity of the solute. The colligative properties studied in this current…

Titan Project-Atmosphere As we discover much more about information of Titan, we gradually completely agree with that Atmosphere of Titan is different, special, and mysterious. Above all, scientists are willing to put their all attentions to study this unknown atmosphere of Titan. This is also a same way that our groups plan to make some missions and built a spacecraft with plenty of instruments, which can send exactly data back to Earth. Hopefully, each instrument really works each other and…

states of matter, properties of water, and experiments of water and ice, there is some evidence that makes this a bit of a complex case. In Chemistry, we generally refer to three states of matter when trying to describe a substance; solid, liquid, and gas. Each of these three states of matter has their own properties and behaviors.…

had to take place. After, the combined gas law had to be utilized and manipulated to find the volume and divide that volume by moles of magnesium. Being close to the theoretical value, 22.4L, it verifies that one mole of all gases occupy 22.4L in any container under standard temperature and pressure. This information could be valuable in many ways. For example, it proves Avogadro’s Law which states that at a standard temperature and pressure, one mole of any gas will occupy the same value which…

Introduction: Enzymes have a huge effect on the human body and other organisms. Enzymes are catalysts that are used to accelerate the reaction process by lowering the activation energy. For this experiment the catechol oxidase was extracted from potatoes. The enzyme is called catechol oxidase because the oxygen is reacting to catechol. Catechol oxidase causes the browning of the fruits and vegetables because the compound is toxic to the bacteria. The purpose of this experiment is to…

Theoretical analysis for HPHX's performance by using dimension analysis theory. Assumptions Steady operation conditions exist. The surface temperature of the condenser section is equal to the temperature of Refrigerant R-22. Properties The exit temperature of air, and thus the mean temperature, is not known. We evaluate the air properties at the assumed mean temperature of 42OC (will be checked later) and 1 atm as following: K= 0.02722 (W/m.K)…

feed mixture require to have different volatilities, so they will separate in gas phases when the temperature has reached their boiling points. All in all, distillation is achieved by vaporization and condensation…

ABSTRACT Flakiness & Elongation index is one of the most prominent criteria that govern behavior and performance of aggregate in the bituminous mixes. The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different percentages from 0% to 50% of flaky &…
