1. Be wary of the main storm hazards. Thunderstorm Hazards (lightening‚ hail‚ tornado‚ downpours of rain flooding‚ downbursts of air gustfronts Hurricane Hazards contain thunderstorms‚ storm surge/coastal flooding‚ high waves‚ coastal erosion 2. Describe the different types of lightning‚ how they form‚ and what happens when they strike something. Cloud-to-cloud lightening: occurs when voltage gradient within a cloud‚ or between clouds overcomes electrical resistance of air. Cloud-to-ground

ENERGY BALANCE Desulphurizer Here Sulphur in Naphtha is made to react with Hydrogen in presence of catalysts to give Hydrogen Sulphide. This reaction takes place at a temperature of 623 K H2 + S Hydrogen and Naphtha are assumed to be stored at 303 K Specific Heat capacity of naphtha is assumed to be 3.5235 kcal/kmol Specific Heat capacity of Hydrogen =(6.62+0.00081T) kcal/kmol K ∆H = ∑ ni ∫ C pi dT = 6.015915 x10 6 kcal hr i Hence heat required to raise their temperature from 303 K to

are made up of an amino group‚ an R group a carboxyl group and an alpha carbon‚ the different R groups of each individual amino acids determines which amino acid they will form. Amino acids bond through covalent peptide bonds this occurs via a condensation reaction‚ which is when one amino acids hydrogen & oxygen (carboxyl group) and another amino acids hydrogen (amino group) react releasing a spare molecule of water (see figure 6) and forming the peptide bond between the carbon and nitrogen‚ going

Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = Evaporation‚ condensation‚ sublimation‚ and precipitation. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = Transpiration‚ surface run-off‚ infiltration‚ and percolation. With or by adding sand and possibly plants to the assignment

which did not both bring condensation when heated and dissolve in water‚ which agreed with our hypothesis because we also thought that sucrose was going to be the only one that wasn’t a hydrate. The only error that we may have encountered in this lab was that when heating‚ the flame was not always the same temperature‚ but I feel as though this did not affect our data much because we didn’t need a set temperature‚ we were only seeing if the substance brought condensation. We could have improved out

philosopher who pronounced the basic substance to be was air through condensations and rarefaction. He was also the first to pronounce the quality pairs hot/dry as well as cold/wet. Anaximenes would use the evidence that at any time air was in a certain area‚ it will become something different‚ such as being in rarefied‚ it turns into fire; if it was condensed‚ it became wind and as it was moving through different condensations‚ it will eventually be turning into clouds‚ water‚ earth and finally

a chain Polymers: a chain of many monomers that are chemically bonded together. How are polymers formed? Dehydration Synthesis (Condensation): two hydrogen atoms and one oxygen atom are removed from the monomers to form water‚ and the two monomers are joined together. How are polymers broken down? Hydrolysis—the reverse of dehydration synthesis (condensation) the reverse of dehydration synthesis. Water added to the polymer‚ unlinking the chain and breaking it back down to its original monomer
