Joule Heat John Doe 4/3/2014 Introduction The objective of this lab is to learn that whenever there is an electrical current in a conductor‚ there is some electrical energy that is converted into heat energy. The heat generated in an electrical circuit is commonly referred to as joule heat. Sir James Joule studies of these separate phenomena lead him to the discovery of the proportionality constant known as the Joule equivalent of heat‚ denoted by J. The Joule equivalent of heat is the amount

Canford Heat is situated in south-west England‚ and it is centred on the large estuary of Pool Harbor in Dorset County. It is the largest lowland heathland in the UK‚ covering 334 ha area and including the Site of Special Scientific Interest (SSSI) it extends on 412 ha. Heathlands have a special status across the Europe (EU Habitat Directive) and heathlands are in the UK especially important as the UK covers 20% of European heathlands. Thus‚ special attention is given to the protection of the heathlands

How to Prevent Heat Stroke Heat stroke can be a risk‚ especially in the summer months. If you want to enjoy the outdoors in hot weather‚ you should keep hydrated and avoid overly exerting yourself in heat and humidity. If you have to be outside‚ drink plenty of fluids and take breaks in a cool place. You should avoid liquids that dehydrate you‚ such as caffeine drinks and alcoholic beverages. Instructions 1. Prevent Heat Stroke o 1 Limit the time you spend outdoors to the early morning

Hess’ Law of Heat Summation Hess’ Law states that: "The enthalpy change for any reaction depends on the products and reactants and is independent of the pathway or the number of steps between the reactant and product". BASICALLY: Hess’ Law states "the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps" >This is also known as the "law of constant heat summation". All it means is that no matter how many steps the chemical

Forced Convection Heat Transfer I. Introduction This laboratory deals with forced convection‚ forced convection can be considered as a staple of heat transfer. That is to say that forced convection can be found in almost any heat transfer problem‚ and thus understanding its importance and how it affects a given problem is one of the more important learning objectives/outcomes of heat transfer. When dealing with forced convection the most important section‚ after understanding how convection

Title: Heat Treatment of Ferrous Objective: To determine the effect of heat treatment on mechanical properties of 1050 Steel. To reveal the microstructures of 1050 steel during heat treatments. Abstract In this experiment‚ we observed how the properties of plain carbon steel vary with the heat treatment condition. We prepared six different samples in three different heat treatment configurations and performed hardness tests on them by using the Rockwell tester and observed the microscopic

The Latent Heat of Vaporization of Water The Latent Heat of Vaporization of Water Aim: The aim is to determine the latent heat of vaporization of water by doing an experiment of boiling water. Theory: The latent heat of vaporization is the amount of energy that is required to transfer a kg of liquid from the liquid state to the gaseous state. This transformation appears‚ when water is heated. The temperature of the water keeps increasing‚ until it
