degrees. • Greenhouse effect is the idea that the earth is a greenhouse‚ and the atmosphere is glass that stops substances exiting or entering. • DARK‚ MATT SURFACES emit more radiation than shiny‚ light ones‚ and absorb radiation better. • Conduction: free electrons are given energy where heated and diffuse – this energy is passed on as electrons collide. o A conductor can pass on this energy much quicker. • Shiny‚ light surfaces reflect radiation the best. • Convection occurs with only

Homeostatic Control of Core Body Temperature Our bodies have processes that happen to keep everything at an even rate. If things get out of balance our bodies tries to bring them back into balance. Homeostasis refers to the processes of keeping internal body environment in a steady rate‚ when the external environment is changed. The aim of this essay is to discuss the internal environment‚ the importance of regulation of core temperature‚ negative feedback and positive feedback and contrast

chill is the perceived decrease in air temperature felt by the body on exposed sin due to the flow of cold air. Wind chill temperatures are always lower than air temperature. The human body loses heat through convection‚ evaporation‚ conduction and radiation. The rate of heat loss by a surface through convection depends on the wind speed above that surface. As a surface heats the air around it‚ an insulating boundary layer of warm air forms agains the surface. Moving air disrupts

Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

On the other hand if some individual touches the metal pan‚ in case it is sufficient thick than one can burn his hand without hot pads‚ it’s related with masses of body and heat conduction. When someone touches one of the hot aluminum racks it no longer has to radiate to reach. He is in direct contact. Heat transfers better through a heat conductive medium. Most Metals transfer heat quickly. Since the human body consists mostly of
