PHYSICS FORM: 4D & 4E TOPIC: THERMAL PHYSICS Temperature determines the direction of net heat flow. It is the property o f an object. It’s the amount of kinetic energy a body possesses. Example Brass rod made hot at one end by placing it in a Bunsen flame‚ while other end is kept away at room temperature‚ there is a net transfer of energy from the high temperature region to the low temperature end. THERMAL EXPANSION (See chp. 16 in Physics Text). Three states of matter are solids

Experiment 1: Thermal Linear Expansion Abstract: The thermal linear expansion of copper and aluminum is the focus of this experiment where the two metals have a tendency to expand their length in response to the change of temperature. Each metals have their own coefficient of linear expansion which describes how the size of an object changes with a change in temperature while the pressure is held constant. We ’re able to determine the theoretical coefficient of linear expansion of the two metals

THERMAL POLLUTION It is one of the pollution that effects on living things and the environment badly. The definition of thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature‚ the change in temperature decreases oxygen supply‚ and affects ecosystem composition

nuclear energy produces thermal energy‚ which is given off as heat. Fission’s heat is used to generate electric power in hundreds of locations worldwide. The sun and other stars use fusion to generate radiant and thermal energy. As stars give off energy‚ they lose mass. Someday humans may be able to harness nuclear fusion as well. Nuclear energy also has other uses. In medicine‚ it is used in radiation therapy to treat cancer. The U.S. Navy uses nuclear energy to power some submarines and large

1. Thermal inertia is a measure of the thermal mass and the velocity of the thermal wave which controls the surface temperature of a material. In heat transfer‚ a higher value of the volumetric heat capacity means a longer time for the system to reach equilibrium. 2. The ocean acts as a massive heat-retaining solar panel. 3. Salinity‚ temperature and depth all affect the density of seawater. 4. A pycnocline is the cline or layer where the density gradient (∂ρ⁄∂z) is greatest within a body of water

THERMAL SENSITIVITY REPORT METHOD Measuring oxygen concentration: One glass vial was filled with 7-13 Artermia. After incubation‚ uncapped at 15oC for 5 minutes‚ the glass vial was sealed underwater and incubated again for another 5 minutes. After this 5-minute incubation‚ a reading of oxygen concentration was taken via a fibre-optic cable held onto a sensor spot on the vial. The vial was then returned to the incubation bath. The first reading represented time zero and subsequent readings

RED CELL PAPER When I think how I would plan out a terrorist attack the first thing that comes to mind is when I worked for a private security company that did security for a nuclear power plant here in Cordova‚ Iowa. They had somewhat of a strong security team but lacked in the areas of the plant that needed the most security. They lacked security for the cooling towers which without could cause the whole plant to come unstable. So there for I’m going to explain how easy it would be to execute
