the second part will determine the number of moles of nitrogen, that will lead to determine the value of R by measuring P, V, and T. Theory/Principles A physical law such as Boyle’s law states that P, the exerted fixed mass of gas at a constant temperature and V, the volume have a relationship. Their kind of relationship is V=f(P) relationship and it is believed that PV go together to remain constant. A water manometer is an instrument used to measure pressure. The model of kinetic theory of…

pyrite. Koslides and Ciminelli (1992) suggested that during alkaline oxidation of sulphides, there is a change from chemical (activation energy > 40 kJ/mol) to diffusion (activation energy < 40 kJ/mol) control as the rate determining step when temperature is above 100°C This led them to conclude that the oxidation is a mixed controlled reaction. Alkaline oxidation of arsenic bearing minerals Arsenopyrite (FeAsS) is the most abundant arsenic containing sulphide mineral. As such, it will be…

Fragmentation occurs when compaction force continues to increase Particles fracture, create multiple new surface sites, additional contact points and potential bonding sites. Particle Bonding: Process of dry granulation relies on inter‐particulate bond formation. Under compaction or high pressure, bonding force between the particles develops by the direct contact between the solid surfaces. The particles can…

Abstract In this study equilibrium isotherms, kinetics and thermodynamics of ciprofloxacin on seven sediments in a batch sorption process were examined. The effects of contact time, initial ciprofloxacin concentration, temperature and ionic strength on the sorption process were studied. The Kd parameter from Linear sorption model was determined by linear regression analysis, while the Freundlich and Dubinin–Radushkevich (D–R) sorption models were applied to describe the equilibrium isotherms by…

implies a process of eliminating heat from a substance. After heat removing, the next stage of the refrigeration process is to pass it out elsewhere in order to fulfill the desired purpose of lessening temperature of that particular place or space. Another aim is to maintain a desired lower temperature. According to the Second Law of Thermodynamics, heat does not pass from the cold place to warm place without the assistance of an outer agent. Therefore, a refrigerator needs to have an outer…

aims to understand how Iron III phosphate (FEPO4) behaves under high temperatures and at which temperature would we start to observe structural transition of Iron III phosphate. As found by the researchers, the temperature where one is able to witness a structural change of Iron III phosphate, a transition from α-β would be at the temperature of 980K. As the researchers have highlighted, there have been substantial high temperatures experiments done on isotopes (AIPO4) and Quartz (SiO4). However…

Sultra the Vixen is a combination curling iron, hot air brush and dryer all in one sleek and beautiful volumizing package. While some other hot air brushes need to be used on slightly damp hair, or require product on dry hair, the Vixen uses hot air to heat the ceramic barrel. This creates a combination of hot air brush and curling iron that can be used on dry or damp hair. Instead of spending over an hour sectioning, blow drying, and curling your hair, you can achieve a beautiful blowout look…

Being the largest organ in your body, your skin works really hard to protect you against germs, pollution and extreme temperatures. It keeps you warm in winters and cool in summers. Your skin is also the first to show indications of an underlying problem in your body and the signs include dryness, oiliness, eczema, sores, moles, bruises, etc. And these are a few of the reasons why you should take care of your skin. Skin care is not just about using expensive skin care products. It entails…

INTRODUCTION: Exercise 3.1 - Osmosis: Toward the start of lab, we found out about diffusion which can happen as active transport or passive transport. Diffusion is known as delivering a net development of solute particles from locales of higher focus to districts of lower concentration. Active transport is the development of an atom over the plasma layer. Active transport is when atoms move against their focus slopes. We discovered that dynamic transport requires vitality, and the motivation…

2600 ppm N2O, balance He, 0.3 Mpa, GHSV-19,000 h-1. Fig.9. The T50 and T100 of different Cs-doped Cu50Ce50Ox catalysts The activities of the catalysts with different Cs content for N2O decomposition are shown in Fig.8, and the T50 and T100 (the temperature at which 50% and 100% conversion of N2O decomposition is achieved) are shown in Fig.9. It’s found that the activity of the Cu50Ce50Ox catalyst is relative low, and T100 of N2O conversion is about 440 oC. The addition of small amount of Cs…
