Water vapor

melting point of -79°C and it is also denser than air therefore when it sublimates to CO₂, it will replace O₂ in the environment and sink to low areas. Dry ice is a result of deposition in carbon dioxide, this process is the phase transition from vapor directly to solid compressed under very high pressure until it liquefies (Kurtus, 2005). After the pressure is released, some of the pressurized gas will release in vapour form. The rest of the substance would expand and convert into the solid…

is retarding force results in the decrease of droplets velocity as they approach the heated substrate. Thermophoretic forces keep most droplets away from the substrate surface and the film grows from the vapor of droplets passing very close to the heated substrate surface as in of chemical vapor deposition as shown in fig. Droplets after collision with heated substrate changes into powdered form. The droplets closer to the heated substrate but not in actual contact improves the efficiency of…

Glacial Melting – Cause, Effect, and Solution People and animals around the world need clean water year-round to drink and to use for growing crops and vegetation. Increased glacial melting is one casualty of global warming, which is caused by increased greenhouse gases like carbon dioxide, water vapor, methane, nitrous oxide, fluorinated gases, and ozone (EPA.gov, 2013;NASA, 2015), which tend to absorb infrared radiation (i.e. heat) that was emitted by the earth’s surface, which would have…

flask, a 100ml receiving flask, a condenser for water to run through, and a thermometer to monitor the temperature. The measurements of the empty flasks were 37.5120g for the distillation flask and 31.1978g for the receiving flask. The mass of the unknown liquid mixture was determined by transferring the mixture into the distillation flask and subtracting the initial…

Hydrogen Peroxide Decomposition Lab Report Objective: By utilising the catalyst of potassium iodide to trigger a decomposition reaction in hydrogen peroxide, how will fluctuation in temperatures will affect the decomposition rate? Hypothesis: Due to the decomposition effect of potassium iodide on hydrogen peroxide, the increased temperature applied will also increase the decomposition rate, because of the more occurrences of collisions which causes the more energy to be produced. Independent…

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 gases helps elaborate one of the most difficult…

it's killing marine life and endangering them. The ocean water is losing pH since its process that keeps pH balanced it's fast enough. We keep putting more CO2 in the air and the ocean is taking it all in. Since the pH levels…

ammonia with acids or known as ammonium salts and contain the ammonium ion, NH4+. NH3 also ionizes to a small extent with metal oxides and the halogens. Like water, ammonia undergoes molecular autoionisation to form its acid and base components, decomposing to NH4+ and NH2- (“CHEM-GUIDE”). Ammonia is combustible in air, producing nitrogen gas and water. The combustion of ammonia is exothermic and usually needs some sort of catalyst to occur. While ammonia is highly stable, it can be decomposed…

radical scavenging methods whereas the antimicrobial activity will be determined using disc diffusion method. Hydrodistillation is used in the extraction of EOs from the C. nardus leaves. Hydrodistillation divided into three types, which are water distillation, water and steam distillation and direct steam distillation. However,…

shrinks and may vanish altogether. When winter comes, the ice cap grows back. Researchers say there might be some liquid water trapped underneath the carbon dioxide ice…
