Ionization energy

In Greek, this is an onomatopoetic word. This means it’s a word that imitates the sounds associated with the objects or actions it refers to (like the word buzz in English sounds like the sound a bee makes when he is flying around). The word zeloo imitates the sound of boiling water, and it literally means to bubble over because it’s so hot! In a positive sense, zeloo is to be zealous in the pursuit of good, to desire earnestly, to strive after, to pursue, to be eager to possess. In the…

data reveal a semiconductor behavior where the resistivity decreases with the increases of temperature. The decrease of the electrical resistivity with increase of temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal atoms act as charge carriers reservoir supply the complex with the free electrons and the metal ion can act as a bridge to facilitate the flow of…

Fig.7, shows that, the insulator behavior of the PVA for pure PVA. But, with increasing the time of reaction there is an improvement in the electrical conductivity of the PVA-Ag nanocomposite films. Fig.7 shows that, the (I–V) characteristic of the samples, and the inset of Fig. 7 shows the relation between the conductivity and time of reaction. Then, the dc conductivity was calculated at the (voltage = 10 V) using the relation. (S/cm) Where (d) is the sample thickness, (A) is the area of…

the unit used to measure the energy-producing value of food. Theoretically, calorie is characterizes as a unit of heat measurement, in nutrition and the kilocalorie is the amount of heat required to raise the temperature of 1kg water through 1˚c. Another definition is that calorie is a unit of measurement that determines the amount of heat released in a food during metabolism. It states the energy value of a food calorie (cal) or kilocalories (kcal). The body needs energy to manage about 1000…

Two computation cases were introduced, one with a polyurethane graft and another with a silicon rubber graft. The computations were done under a pulsatile flow. Both cases were computed under maximum peak pressure as mentioned in the method section. The flow volume rate is expressed by integrating on surface as followed: Q=∬_A^ ▒v.dA (5) By integrating flow volume rate in time…

Cold Packs What are cold packs used for? 1. Cold packs are often used to treat painful injuries, such as a sprain or to ease swelling from minor injuries; cold packs come in many different variations some are made of gel that turn into icepacks when stored in cold, dry places, others are designed to freeze when pressure is applied to the gel pack where no freezing is required, the cold pack is used to slow down the blood flow to an injury so it doesn’t potentially get any worse. How the contents…

Team Experience Working with others has not been difficult for me. Two reasons I believe this occurs are I always challenge myself to do great work and I am also patient with other people. Unfortunately, these are two traits I suspect contributed to a challenging team experience, from which I was able to learn a lesson. I believe these are quality traits, essential for me to be able to do any good group work with other people. As such, I will need to continue to employ them, but in a…

Based on our observations from the Zinc and Hydrochloric Acid Lab, we concluded that the chemical reaction that occurred was exothermic and a single displacement reaction. The experiment consisted of zinc (Zn) and hydrochloric acid (HCl) being mixed in a test tube immersed in water. First of all, bubbles were produced during the reaction. Also, a white powdery substance was produced with properties different from those of any reactant. The bubbles suggest that the reaction was a chemical…

end up fitting when it is heated or the ring might be too big for the ball after the ball is cooled. This might affect our results by thinking that the brass ball contrasted a lot after being cooled by the water when it was really just the thermal energy that made the ring…

Kinetic and potential energy play an essential role in the segments or phases in a heating or cooling graph representing an exothermic or endothermic process. Kinetic energy is the energy of a system that is in motion of the particles in the system. Potential energy is the energy of a system in which it represents the arrangement of the particles of the system. Kinetic energy and potential energy never increase or decrease at the same time, however, when one energy is changing the other remains…
