Why does a black body absorb more heat than a shiny body? When you step inside a warm ski lodge on a cold day, you find your eyeglasses fog. Why does this occur? Explain why most materials become less dense as their temperature is increased. ...
When this happens, the earth tends to absorb more heat than it used to before and the result is that, on top of the already warm temperatures, a rise in ground temperature also takes place, sometimes accompanied by rainfall, and this may set the stage for the creation of clouds. The gre...
Blackcurrant is often spelt as one word but is also written as black currant. This means that if you are looking for dried blackcurrants, it is always worth checking the packaging carefully to ensure you will be buying the berries that you want, rather than currants for a cake. Perhaps t...
Explain the heat transfer through conduction. What is the definition of motion in physics? Describe various types of motion. What do negative joules mean? Why do black objects absorb heat and retain heat better than white objects? Can the kinetic energy of a system be negative? Explain....
When the refrigerant levels are insufficient, the evaporator coil may not be able to adequately absorb heat, causing the coil to become excessively cold and freeze over. Once the ice melts, it can overwhelm the drain pan and result in water leakage. Addressing low refrigerant levels typically ...
Because heat is used, however, there is a risk of skin burns and subsequent scarring. Expert Gauglitz, therefore, warns against going to the beauty salon for treatment – even if the treatment is significantly cheaper than at the dermatologist’s: “Good cooling is crucial to protect the ski...
If the dew point rises, it means there’s more moisture in the air. The dew point is always equal to or lower than the current air temperature. When the dew point is close to the air temperature, the relative humidity is high, leading to a muggy and uncomfortable feeling. Why Is Some...
needs and then grown like crops rather than manufactured with energy-intensive industrial processes, like the BioMASON bricks. DNA could be manipulated to give materials special properties—for example, the ability to absorb carbon dioxide from the air, reflect heat during the summer, or glow at ...

to absorb heat from the sun to heat water, you need large, flat, back surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt(柏油) roads ?
