Introduction Specific heat is defined as the measure of the ability of a substance to change temperature. Specific heat of a substance is the heat needed to change the temperature of 1 gram of a substance once degree Celsius. The more Joules (unit of heat) needed‚ the higher the specific heat will be. The goal is to determine specific heat of a soil sample as compared to water. This difference has many ramifications regarding our climate‚ with local and global. Hypothesis I predict that after

Environmental determinism is an idea that the physical environment influences human progress towards specific routes. Hippocrates‚ Airs‚ Water‚ and Places‚ and Jared Diamond’s‚ Guns‚ Germs‚ and Steel‚ each offer a view of environmental determinism and suggests a link between the physical environment and medical discourse and racial classification/inequality. Hippocrates Airs‚ Water‚ and Places was one of the first major works on environmental determinism. It concentrated on medical climatology‚ geography

HEAT TRANSFER Heat transfer‚ also known as heat flow‚ heat exchange‚ or simply heat‚ is the transfer of thermal energy from one region of matter or a physical system to another. When an object is at a different temperature from its surroundings‚ heat transfer occurs so that the body and the surroundings reach the same temperature at thermal equilibrium. Such spontaneous heat transfer always occurs from a region of high temperature to another region of lower temperature‚ as required by the second

Heat exchanger A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids‚ between a solid surface and a fluid‚ or between solid particulates and a fluid‚ at different temperatures and in thermal contact. In heat exchangers‚ there are usually no external heat and work interactions. Typical applications involve heating or cooling of a fluid stream of concern and evaporation or condensation of single- or multicomponent fluid streams. In a few heat exchangers

CASE STUDY: Decision time at Hilton Hilton’s current distribution policy is causing its original competitive advantage of being the industry leader to deacrease. As a matter of facts‚ the traditional channels Hilton is using (such as hotel wholesaler‚ tour operators‚ global distributors systems and third-parties websites) plus the increasing popularity of Expedia-like sites has led the company to loose market shares (caused by the introduction of smaller independent hotel chains). Therefore‚ considering

Technology of the Insulin Pump For many years‚ people who have been diagnosed with diabetes typically do not live a long life. “Diabetes mellitus is a condition in which the pancreas no longer produces enough insulin or cells stop responding to the insulin that is produced‚ so that glucose in the blood cannot be absorbed into the cells of the body”(Farflex). There have been many advances in the technology of diabetic supplies; this includes the insulin pump. “Insulin pumps are a medical device

1. INTRODUCTION An engine is a device which transforms one form of energy into another form. Most of the engines convert thermal engine to mechanical work and therefore they are called heat engine. Heat engine can be broadly classified into two types. i. Internal combustion engine ii. External combustion engine 1.1 CLASSIFICATION OF INTERNAL COMBUSTION ENGINE:- This type of engine is again classified into two types. i. Rotary ii. Reciprocating The reciprocating engine is a highly complex

HEAT TRANSFER MECHANISMS Heat energy is being transferred from one location to another because of a temperature difference. The three mechanisms for heat transfer are: • Conduction. When you grip the hot handle of a pan on a stove‚ you feel conduction in action. Heat flows from the pan and along the length of the handle to its cooler free end. This is because one end of the rod is held at the high temperature‚ and the other end stays at the lower temperature. Although the rod itself doesn’t
