Explain the terms convection and conduction? What will happen to the convection currents in the mantle if the Earth's interior eventually cools down? What are the convective and radiative zones? What do you understand by the free convection boundary layer and how does it affect heat transfer?
How does counter-current heat exchanger conserve heat? Heat Exchangers: The use of heat exchangers in industrial and commercial processes is a long standing practice. They are used any time liquids (and sometimes gases) need to be cooled without interacting with other compounds or the atmosphere....
convectiontropical climateThe response of the Madden‐Julian oscillation (MJO) to ocean feedbacks is studied with coupled and uncoupled simulations of four general circulation models (GCMs). Monthly mean sea surface temperature (SST) from each coupled model is prescribed to its respective uncoupled ...
How does temperature affect the kinetic energy of gas molecules? Kinetic Theory of Gases: The Kinetic Theory of Gases is a simple model that relates microscopic properties (such as average speed) of molecules to macroscopic properties (such as pressure or temperature) of gases based on the assump...
How does the speed of sound on a warm day differ from that on cold days? How would the whiteness of snow appear if Earth's atmosphere were several times denser? How is it possible for a fabric (textile) to conduct the 3 modes of heat transfer (conduction, convection, and radiation)...
If you’re remodeling, consider that convection ovens cook 25 to 30 percent faster than conventional ovens, saving time and energy. Another green habit is to always use the right appliance for the job. For example, use a toaster to heat up your frozen waffles instead of heating up a large...
Most of the movements of air currents on a global scale happen in the Earth's upper atmosphere. As the sun-warmed air rises, it diverges in the troposphere and moves toward the Earth's poles in several giant loops called circulation and/orconvection cells. ...
In a total solar eclipse, the Moon completely covers the Sun, revealing the Sun's corona. An annular eclipse occurs when the Moon is farther from the Earth, resulting in a ring-like appearance of the Sun around the Moon's silhouette. Does a solar eclipse affect humans? A solar eclipse ...
The plates are rigid slabs almost floating along in the asthenosphere, but scientists still aren't sure what causes the plates to move. They know it's somehow related to convection currents in the continental crust, in which hot materials rise upward as cooler materials flow downward, but they...
How does convection affect air currents? How do air currents move about the Earth? How do air currents differ in pressure? What affects air currents and ocean currents? How are air currents winds related to ocean currents? How do prevailing winds affect the movement of air masses?
