Abstract Different substances react in various ways when exposed to heat. The amount of energy necessary to heat a certain amount of water by one degree is different than that of another liquid or substance. The technical term used to determine this characteristic is called heat capacity or specific heat capacity. The purpose of this experiment is to find the heat capacity of water‚ orange juice‚ and olive oil. A couple of very specific equipment is needed in order to complete this experiment‚ such as:

Experiment 1 The Heat Capacity Ratio of Gases Purpose The purpose of this experiment is to calculate the heat capacity ratio of gases‚ Helium‚ Nitrogen and Carbon Dioxide‚ and compare with their theoretical values. Introduction Thermodynamics is the study of heat as it relates to energy and work. There are various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy required

Specific Heat Lab Report “Here are the facts we confront; No one is against conservation. No one is against alternative fuel sources.” – J. D. Hayworth Research Question: Does the number of hydrocarbons that a fuel is composed of affect how much it will ignite? If so‚ consider the following: What is the quantity and concentration of the combustion that is released and how can that be measured in other (more coherent) means? These are the fuels that were seasoned throughout the

search- specific latent heat Q. Value for the specific latent heat of fusion of water: Specific latent heat is where the amount of energy (in joules) needed to change the state of 1Kg of a substance is called its specific latent of heat. You can calculate the amount of energy needed using the equation: energy (J) = specific latent heat (J/Kg) X mass (Kg) Material Specific heat of fusion (J/Kg) Specific latent heat of vaporisation (J/Kg) Water 334000 2260000 Lead 24500 871000 Ethanol

Specific Heat: The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. The relationship does not apply if a phase change is encountered‚ because the heat added or removed during a phase change does not change the temperature.

the experiment aimed to determine the specific heat of two different metals‚ Lead and Zinc‚ in order to calculate their individual atomic weight. Theory The calorimeter consists of a metal outer cup‚ a removable metal inner cup‚ which is held in place by a rubber ring‚ and an insulating lid with a small opening for a thermometer. It is a closed system as the air between the inner cup and outer cup insulates the water and heated metal‚ so‚ ideally‚ all heat is contained within the calorimeter (1)

Production Capacity It is highly imperative that management must formulate a strategic plan for operations before any production is carried out. This is basically important in avoiding possible hindrances and excess in capacity. Under capacity may force the firm to cancel production schedules or excess can be fatal due to a broadened fixed cost. Both really would be a financial burden to the firm. Some procedural strategy can be adopted to minimize ill effects of capacity-related problems

HEAT GENERATED IN APPLIANCES Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.The heating appliances has a heating element like resistors. The resistorsconvert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity. Those devices who produced heat‚ the Nichrome wire is an element who is responsible for heating . when we say nichrome
