compound using the colligative property of Freezing Point Depression. The way we did this was first finding the temperature at which ice crystals form for just regular BHT. Luckily thanks to our TA we were given temperature probes so we could pinpoint exact temperatures. We found that the temperature at which crystallization of BHT was 68.9 Celsius in our lab. After finding temperature of BHT we were tasked with adding the solute cetyl acid to our BHT mixture. We then heated and melted the two substances

CLIMATE CHANGE What does the climate mean? Climate‚ like weather‚ describes the state of the atmosphere in terms of factors such as temperature‚ rainfall‚ and wind patterns. Whereas the weather describes conditions as measured in hours‚ days or weeks‚ the climate is average weather conditions measured over the longer term: months‚ years or decades. What is climate change? Any process that causes adjustments to a climate system – from a volcanic eruption to a cyclical change in solar

tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons The Tundra Biome is one of the most unique Biomes in the world. Covering one tenth of the earth’s land area it is a substantial Biome. Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi‚ meaning treeless plain. It is noted for its frost-molded landscapes‚ extremely low temperatures‚ little precipitation‚ poor nutrients‚ and short growing seasons. Major problems With

In other way vapour cycle system his also help to reduced the humidity of the air entering the cabin while aircraft on the ground and as the temperature of the air is reduced the moisture condenses on the fin of the evaporator then water droplets blown from the evaporator by the air stream and are collected in a water trap and drained away. Vapour cycle cooling system works with 5 components that

factors that affect heat loss from a body. All athletes become hot during exercise and need to be aware of how fast their bodies will cool down after the exercise. In extreme conditions the continued drop of body temperature may cause hypothermia. Hypothermia is caused by the core body temperature dropping below 35degrees. This is why it is important to how quickly the body loses heat and what affects it. Heat is lost from the body in 3 different ways conduction‚ convection and radiation. Conduction

THE PIRATES OF THE SILVERLAND - PALM OIL PIRACY Summary of the case: Palm Haul Sdn Bhd (PHSB) established in 2002 at Taiping Perak. It was a small and medium sized enterprise in crude palm oil (CPO) transportation business. PHSB was managed by En.H.Rossly and son in law of its founder‚ Datu S. Najeed. PHSB was facing the same problems likes others transportation companies which is drivers embroiling in oil piracy. The transportation companies will bear the responsibilities of compensation of the

the system was measured. The rate of heat output and the coefficient of performance are to be determined. A sketch of the vapor-compression cycle on a pressure-enthalpy diagram is also to be presented. In order to perform this analysis the temperatures at the inlet and outlet of the condenser and evaporator were measured for both the refrigerant and the water. The flow rate of the refrigerant through the system was measured and assumed to be constant throughout. The flow rate of the water was

Does the temperature outside affect how fast molecules move inside objects? Charles Law helps us understand how molecules move in different temperatures. It states that increasing the temperature of a constant pressure volume of gas causes individual gas molecules to move faster (Andrew Staroscik Staroscik 9/19/16)‚ and the volume is proportional to the absolute temperature of a gas at (Todd Helmenstine 10/16/16). Therefore‚ as the temperature increases‚ so does the speed of the molecules‚ and when
