1 Honors Laboratory: Specific Heat and Conservation of Energy When energy in the form of heat Q is added to a material‚ the temperature of the material rises. Note that temperature‚ in units of degrees Celsius (°C) or Kelvin (K)‚ is a measure of how hot or cold a substance is‚ while heat‚ in units of joules (J) or calories (cal)‚ is a measure of its thermal energy. 1cal = 4.19J. A measure of the efficiency with which a substance can store this heat energy is known as specific heat capacity‚ or simply

Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

We can sidestep this molecular picture by dealing with objects as a whole‚ and treating the energy transfer as the flow of heat‚ rather than kinetic energy transfer among particles. |Specific Heat for Various Materials | |Material |Specific Heat | | |(J/kg C°) | |Water |4186 | |Aluminum |900 | |Steel

between passive and active immunity. Please list two examples of each. What are the advantages of active immunizing agents? Answer: 1/ Explain the difference between passive and active immunity. Please list two examples of each. Active immunity occurs when a person develops a permanent immunity to a disease‚ while passive immunity occurs when a person develops a short-term immunity‚ both active and passive immunity can be natural or artificial. Artificial active immunity is induced by a vaccine

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

Microbes: Adaptation and Immunity One of humanity’s biggest blunders is the frequent use of antibiotics against viral infections‚ which include influenza‚ colds‚ herpes‚ etc. Not only do these antibiotics have absolutely no effect to both the patient’s condition and the infection itself‚ these also promote antibiotic resistance. This blunder is aided by the accessibility when it comes to antibiotic purchase. What is Antibiotic Resistance? Antibiotic resistance is a form of drug resistance which

Specific Performance MT311 Business Law Part I There are four situations we have to review in terms of specific performance and possible breach of contract. First we must understand the elements of specific performance then we can evaluate how they relate to each scenario. “In some situations‚ damages are an inadequate remedy for a breach of contract…equitable remedies include rescission and restitution‚ specific performance‚ and reformation” (Miller & Jentz‚ 2009). Specific performance

A specific phobia is an irrational fear of a usually harmless object‚ place or situation. This fear leads people to dread confronting everyday situations‚ or avoid them altogether. ‘The most common specific phobias are agoraphobia‚ the fear of crowded places and arachnophobia‚ the fear of spiders’ (Davenport‚ 1992‚ pg. 239). The main symptoms of person suffering from specific phobia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV)‚ include ‘a marked and persistent

Specific gravity What is specific gravity? Archimedes discovered that the weight of body in air minus its weight in water is equivalent to the weight of the water displaced by the body. Specific gravity is defined as "The weight of a body compared with the weight of an equal amount of pure water at 4°C (4°C is the temperature at which water is densest). When a body is placed in water‚ the volume of water displaced is equal to the volume of the body. When the body is placed in water that it
