In this experiment‚ the Independent Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because

Heat Stress in the Work Place! Eastern Kentucky University Heat Stress is the exposure to extreme heat or working in hot environments. Workers who are exposed to this may be at risk of heat stress. Heat Stress can result in occupational illnesses and injuries. “Heat stress can result in heat stroke‚ heat exhaustion‚ heat cramps‚ or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms‚ fogged-up safety glasses‚ and dizziness. Burns may

Beat the heat with aircon repair Summer times can be difficult to manage in the hot regions and this calls for a nice chilled breeze of the air conditioner. While this may be the best prospect at this time‚ the problem comes with the appliance itself. Air conditioners just like any other electronic appliance are prone to problems and malfunctions. The malfunctions in this case can be quite bad considering how complicated the appliance is and this means that it requires professional help and not a

Common casting defects and there possible causes; There are many different types of casting methods used within jaguar‚ and with all these different methods come different kinds of defects. Defects can be the result of anything

Conclusions The purpose of this experiment was to find the relationship between a substance’s specific heat and its atomic weight. In the lab‚ the substances with the higher atomic weights had less specific heat. From this‚ we can conclude that specific heat and atomic weight have an inverse relationship‚ meaning as one decreases the other increases. The reason for this is because if atoms are small‚ or light‚ they have the ability to pack tightly together‚ leaving almost no space between them

Title: Specific Heat Capacities of Metals Experiment Date: 3/28/2012 Report Date: 4/4/2012 Purpose: The purpose of the lab is to measure the specific heat capacities of aluminum‚ steel and brass. Theory: The amount of heat (ΔQ) required to change the temperature of an object is proportional to the mass (m) of the object and the temperature change (ΔT) of the object. ΔQ= cmΔT where c is called as the specific heat capacity of the material. In the calorie units system the unit of quantity

said that this is a method of heat treatment to strengthen the material‚ shape and improve the ability of the engine from the material. The process of heating and cooling is done on extremes of temperature to get desired results. It is very useful to the manufacturing process‚ but the heat treatment is not only useful for manufacturing processes but also to improve the quality‚ performance and characteristics of the product. It contains the process of heat treatment including heating by means of

Description of theory Age or Precipitation hardening is a widely used heat treatment method that is done to raise the strength (including the yield and ultimate tensile strength) of malleable materials such as Aluminum. In precipitation hardening‚ the formation of a very fine and uniformly distributed second phase particles in
