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

Equity Valuation: Discounted Cash Flow and Residual Income Models Introduction Valuation plays a very important role when companies are trying to increase their value‚ raise money‚ acquire another firm or sell a subsidiary‚ also when a company decides to go public. Managers‚ investors and shareholders need to have the most accurate and reliable information in order to make decisions‚ that is why valuation is a fundamental exercise in corporate finance. It is pretty evident that whatever

of how good a material is at conducting heat is known as its thermal conductivity. Thermal conductivity is defined as the rate at which heat flows through a certain area of a Object of the experiment is to determine the thermal conductivity of metals and insulation body.materials and also to demonstrate that heat flow is directly proportional to temperature differences between faces and to cross sectional area. Thermal conductivity is defined as:

Thermal Conductivity Heat can be transferred in three different ways: convection‚ radiation and conduction. Conduction is the way heat is transferred in a solid‚ and therefore is the way it is transferred in a heat sink. Conduction occurs when two objects with different temperatures come into contact with one another. At the point where the two objects meet‚ the faster moving molecules of the warmer object crash into the slower moving molecules of the cooler object. When this happens‚ the faster

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 Expansion happens a lot in everyday life. When something is heated and expands this is Thermal Expansion. The way Thermal Expansion works‚ is when it is heated the atoms expand‚ and then when it is cooled it shrinks. Several examples of Thermal Expansi Thermal Expansion happens a lot in everyday life.

nuclei are split. It is also released during fusion‚ when hydrogen nuclei combine to form a helium nucleus. In fission and fusion‚ 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
