Compare and Contrast

While penguins are technically birds, they have many distinct attributes that set them apart from the much of the animal class Aves. Penguins thrive in many different climates including tropical and temperate zones. These animals can survive temperatures below -100 degrees Fahrenheit. Antarctic penguins have a three-tiered insulation system. First, they have feathers that act like tiles on a roof, with longer feathers overlapping smaller, fluffier ones. In essence, water-proofing. Beneath that, penguins have a thick layer of fat that…

Protective Equipment Is to Reduce Employee Exposure to Hazards

Fire is the rapid oxidation of a material in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.[1] Slower oxidative processes like rustingor digestion are not included by this definition. The flame is the visible portion of the fire. If hot enough, the gases may become ionized to produce plasma.[2] Depending on the substances alight, and any impurities outside, the colorof the flame and the fire’s intensity will be different. Fire in its most common form…

Temperature Dependent Impact Tests

Purpose This lab was performed to fully comprehend the temperature dependency of the fracture toughness of the Aluminum and Steel. It was also executed to discover the ductile-brittle transition of each. Summary The experiment solidified the hypothesis that the 6061 aluminum has no ductile-to-brittle transition do to its FCC crystal structure. The 1018 steel has a ductile-to-brittle transition temperature of -31ºC due to its BCC crystal structure. Results Figure 1: Graph of fracture energy vs. temperature for entire class data…

Basic Control Mechanisms of Thermoregulatory Process in Livestock

Introduction Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different (Wikipedia, 2012). Thermoregulation could also be referred to as the mechanisms and control systems used by the body to balance thermal inputs and thermal losses so as to maintain its core temperature nearly constant (Monique, 2002). This process is one aspect of homeostasis: a dynamic state of stability between an animal’s internal environment and its external…

Heat of Neutralization

The purpose of this lab was to: * Determine the heat of neutralization for the reaction of sodium hydroxide (NaOH) and hydrochloric acid (HCI). Requirement The heat of neutralization (∆Hneutzn ) is the heat transferred when 1 mol of an acid reacts with 1 mol of a base. This heat is generally reported in either kilojoules per mole (kJ/mol) or kilocalories per mole (kcal mol). The reaction of HCI and NaOH solutions is shown in Equation 1. HCI(aq) + NaOH(aq)…

Balloons Paper

Why does a hot air balloon float even though it is so heavy? Hot air balloons float because the buoyancy force of the hot air is more than the weight. Buoyancy occurs because the hot air has a lower density than the cooler outside air. This lower density air weighs less than the air it replaces and that difference is the buoyancy. What makes balloons float when they are full of air but not float when they are deflated? Balloons…

Ti Chemical Reaction in Automobiles

There are over one billion of cars around the world, getting people where they want to go. Therefore, automobile transportation became much more important in everyone’s daily life. Chemistry made the automobiles to work. The chemistry and chemical reactions used in many parts of the automobiles. The role of chemistry in the automobile includes air bags, starting a car, gas, windshields, combustion and batteries. The most important among all these is keeping the automobile’s engine from getting too hot or…

Effects of Climatic Elements on Livestock Production

INTRODUCTION Climatic elements have direct effect on the system of animal production, body physiology and animal behaviour, feed supply and quality, proliferation of pests and parasites as well as preservation of animal products (Samson et al., 2011) A number of climatic elements such as temperature, rainfall, humidity, radiant energy, air movement, light, altitude etc. greatly influence and interact with the performance of livestock production. Similarly, they also cause major effects on animal physiology, behaviour and productivity through their individual or…

Discussion of Joel

1.The mechanisms of heat loss contributing to Joel’s feelings of coldness are conduction, due to the loss of his hat somewhere on the trail and also his wet clothes; convention, which is happening because of the cold wind blowing; and lastly evaporation which is occurring as he breathes in the cold air and exhales it as warm moist air. 2.To help Joel maintain a normal body temperature, his body will begin to send signals to conserve and generate heat. This…

Pre Lab Report Density of Liquids and Solids

Purpose of the experiment: The purpose of this lab is to help understand how to resolve the density of liquids and solids. Also, the lab is supposed to teach us how to record lab data and how to measure volume and mass the correct way. Lastly, it’s designed to help us understand significant values and its relationship to measurements and data recording. Lab Techniques: One technique that will be used during this lab is comparing the accuracy (absolute & percent…

Infrared Film and Thermography

Thermogram of a traditional building in the background and a “passive house” in the foreground Infrared thermography (IRT), thermal imaging, and thermal video are examples of infrared imaging science. Thermal imaging cameras detect radiation in the infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 µm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects above absolute zero according to the black body radiation law, thermography makes it possible to see…

Thermistor Study

A thermistor is a type of resistor whose resistance varies significantly with temperature, more so than in standard resistors. The word is a portmanteau of thermal and resistor. Thermistors are widely used as inrush current limiters, temperature sensors, self-resetting overcurrent protectors, and self-regulating heating elements. Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is generally a ceramic or polymer, while RTDs use pure metals. The temperature response is also different; RTDs are useful…

Heat Transfer and Temperature

Question 1: A 50 mm diameter, thin wall metal pipe covered by 25 mm thick layer of insulation (ki = 0.085 W/m.K) and carrying a superheated steam at atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC, and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s,…

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…
