 | Heat Transfer by Radiation Thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. |
| Heat transfer by Conduction Heat conduction is a mode of transfer of energy within and between bodies of matter, due to a temperature gradient. Conduction takes place in all forms of ponderable matter, viz. solids, liquids, gases and plasmas. |
| Heat Transfer by Natural Convection Convection is one of the major modes of heat transfer. Natural or free convection is caused because of density difference in solids or liquids or gases due to temperature differences under the influence of gravity. |
| The Study of Phase Change Heat transfer with phase change is the phased transition of heat in the medium such as; water-to-ice and steam,steam-to-water, or ice-to-water and involves significant energy. This occurs through, boiling, condensation,freezing and melting, and sublimati |
| Black Body Radiation: Determination of Stefan's Constant Stefan’s constant is a physical constant denoted by the Greek letter ÃÆ’. This is the constant of proportionality in the Stefan–Boltzmann law, "The total energy radiated per unit surface area of a black body in unit time is proportional to the fou |
| Newton's Law of Cooling Newton's Law of Cooling states that the hotter an object is, the faster it cools. More precisely, the rate of cooling is proportional to the temperature difference between an object and its surroundings. |
| Lee's Disc Apparatus Aim of this experiment is to determine the coefficient of thermal conductivity of a bad conductor using Lee's disc apparatus. Lees' disc apparatus consist of metallic disc (say D) and resting on it is a 5 cm deep hollow cylinder (Steam chamber) |
| Thermo Couple-Seebeck Effect An interesting phenomenon applied in the field of instrumentation is the Seebeck effect, which is the production of a small voltage across the length of a wire due to a difference in temperature along that wire. |
