transferred by warm liquids or gases. Warm air is less dense than cold air because particles have more energy so they spread further. So the hot air rises and transfers heat and the cold air replaces it Radiation: all objects give out and take in thermal radiation which is also called infrared radiation. The hotter an object is the more infrared radiation it emits. It travels in waves not involving any particles‚ which is why the heat from the sun can travel through space. If the body gets to hot

The demand for insulation has increased over the past few decades. No matter in which part of the world you live‚ insulation can bring you comfort and happiness. Why do I say so? Well‚ people who live in hotter parts of the world don’t worry much about insulation‚ but they should. Why do I say so? Did you know that people who live in hotter parts of the world waste so much money on air conditioning (energy bills?) Foilboard is a new type of insulation that can be used in various climates. OK‚ let’s

GASEOUS DISCHARGE LAMPS: A gaseous discharge lamp is essentially a glass or quartz envelop containing two electrodes and a small quantity of gas or vapour at a low pressure. In these lamps light is obtained by applying an electric potential difference to a gas or vapour contained by the lamp under a suitable pressure. Due to application of electric potential difference gas gets ionised and an electric current flows; the tube is filled with a luminous discharge. The light spectrum

designing‚ or operating‚ heat processes need knowledge of the thermal properties of the foods under consideration. Food thermal properties can be defined as those properties 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
