physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces changes of

HEAT GENERATED IN APPLIANCES Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.The heating appliances has a heating element like resistors. The resistorsconvert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity. Those devices who produced heat‚ the Nichrome wire is an element who is responsible for heating . when we say nichrome

Imagine waking up each morning having to sweep up dust that blew into homes at night. Nearly starving from lack of food and water then going broke and living without a home with family’s to care for. We’ll that was life during the Dust Bowl having to face the Great Depression and loving in the Southern Plains.The Dust Bowl was a very unexpected tragedy that hit America in the 1930 lasting a whole decade. The dust bowl accrued mostly of high climates mixing with the broken down jet stream in Mexico

ubiquitous computing researches. Smart dust is a tiny dust size device with extra-ordinary capabilities. Smart dust combines sensing‚ computing‚ wireless communication capabilities and autonomous power supply within volume of only few millimeters and that too at low cost. These devices are proposed to be so small and light in weight that they can remain suspended in the environment like an ordinary dust particle. These properties of Smart Dust will render it useful in monitoring real world

The Dust Bowl was the name given to the Great Plains region devastated by drought in 1930s depression-ridden America. The 150‚000-square-mile area‚ encompassing the Oklahoma and Texas panhandles and neighboring sections of Kansas‚ Colorado‚ and New Mexico‚ has little rainfall‚ light soil‚ and high winds‚ a potentially destructive combination. When drought struck from 1934 to 1937‚ the soil lacked the stronger root system of grass as an anchor‚ so the winds easily picked up the loose topsoil and swirled

Sawdust or wood dust is a by-product of cutting‚ grinding‚ drilling‚ sanding‚ or otherwise pulverizing wood with a saw or other tool; it is composed of fine particles of wood. It is also the byproduct of certain animals‚ birds and insects which live in wood‚ such as the woodpecker and carpenter ant. It can present a hazard in manufacturing industries‚ especially in terms of its flammability. Sawdust is the main component of particleboard. Contents [hide] 1 Practical uses 1.1 Use in food 2 Health
