Black objects absorb more heat and also radiate more heat than white or polished ones.Give a few applications related to both the concepts. |
|
Answer» Black objects HEAT up faster than shiny objects ,although they cool down fast too. Black is a good absorber because it absorbs all kind of EMF we have. When any heat falls down on white or shiny objects it BOUNCES back,but when it falls on black objects,its all retained . EXAMPLES of applications can be; 1.Solar PANELS the solar panels are painted black so that they can ABSORB heat at a faster rate. Moreover,they're painted with a shiny top coating so as to reduce the rate at which heat is lost to the atmosphere. 2. Cloth selection During summer,people wear white or shiny clothes as they're likely to absorb less heat,while during winter people wear dark clothes so as to absorb any available heat that is available. |
