Depending upon the application, a higher temperature may open a contact (as in a heater control) or it may close a contact (as in a refrigerator or air conditioner). The electrical contacts may control the power directly (as in a household iron) or indirectly, switching electrical power through a relay or the supply of natural gas or fuel oil ...
The dry-bulb temperature (DBT) is the temperature of air measured by a thermometer freely exposed to the air, but shielded from radiation. [1] The dry-bulb temperature is the temperature that is usually thought of as air temperature, and it is the true thermodynamic temperature. It is directly proportional to the mean kinetic energy of the air ...
A kitchen oven, at a temperature about double room temperature on the absolute temperature scale (600 K vs. 300 K) radiates 16 times as much power per unit area. An object at the temperature of the filament in an incandescent light bulb —roughly 3000 K, or 10 times room temperature—radiates 10,000 times as much energy per unit area.
However, on country radio it became much more commercially successful, climbing all the way to No. 2, where it peaked for one week, outpacing the peak of 43 set by the recording Rimes released. Consequently, Yearwood's version was among the top 20 biggest country singles of 1997, while Rimes's version was the ninth and fifth best- charting ...
