    controlling the transfer of heat in a specified food. These properties are usually classified (Perry and Green‚ 1973) into thermodynamical properties‚ viz‚ specific volume‚ specific heat‚ and enthalpy; and heat transport properties‚ namely‚ thermal conductivity and thermal diffusivity. When considering the heating or cooling of foods‚ some other physical properties must be considered because of their intrinsic relationship with the ‘‘pure’’ thermal properties mentioned‚ such as density and viscosity

    Thermal Conductivity of Metals and Non-metals 1. Introduction Thermal conductivity is a physical property of materials of great importance. Unlike some physical properties‚ however‚ thermal conductivity cannot be directly measured. In order to determine a material’s thermal conductivity‚ intermediate quantities must be determined from which the conductivity may be ultimately calculated. The objective of this lab was to determine the thermal conductivity of metals. To do so‚ it was necessary to study

    solid substance that has a conductivity between that of an insulator and that of most metals‚ either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors‚ notably silicon‚ are essential components of most electronic circuits. 1. A semiconductor is a material which has electrical conductivitybetween that of a conductor such as copper and that of an insulatorsuch as glass.  semiconductor is a material whose electrical conductivity is between that of a conductor

    This is Because CNTs has unique properties such as high aspect ratio‚ lightweight‚ high mechanical strength‚ good thermal and electrical conductivity and excellent tribological behavior [21]. However‚ the results were not favorable due to the poor compatibility of POM with other materials as a result of high viscosity‚ especially with bulk materials [22]. Therefore‚ Yousef et al.

    The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by coal based steam power plants or nuclear power plants

    while excluding open loops. Direct exchange systems are significantly more efficient and have potentially lower installation costs than closed loop water systems. Copper’s high thermal conductivity contributes to the higher efficiency of the system‚ but heat flow is predominantly limited by the thermal conductivity of the ground‚ not the pipe. The main reasons for the higher efficiency are the elimination of the water pump (which uses electricity)‚ the elimination of the water heat exchanger (which

    Transport Phenomenon (Electrical and Thermal) in two allotropic forms of Carbon (Diamond and Graphite) Graphite and Diamond both are formed from carbon (two allotropic forms of carbon). Though they have similar constituent element‚ they differ a lot in their properties. Diamond is a good thermal conductor but a bad electrical conductor‚ while graphite is a bad thermal conductor but a good electrical conductor. This is one example of their property difference. The difference in their properties
