Wind is caused by differences in air pressure. What makes air pressure different? Temperature differences. Color differences. Size differences.相关知识点: 试题来源: 解析 答案:Temperature differences。温度差异导致气压不同。选项 B 颜色差异与气压无关;选项 C 大小差异也与气压无关。
Why does the pressure of gas enclosed in a rigid container increase as the temperature increases? If the velocity of every molecule in a fixed volume of gas were doubled, few containers would be strong enough to hold the gas. True False Explain. ...
I drove from North Carolina to Ohio yesterday (400 mi total trip) and after the 3rd charge, the battery temp gauge was in the unhappy range (one segment of red was showing), although I did not get any warnings on the dash about it. What happens when it gets "too hot"? I am assum...
The temperature of an ideal gas increases from 20 deg C to 40 deg C while the pressure stays the same. What happens to the volume of the gas? Is it possible to increase the temperature of a gas without adding heat to it? If so, how? What effect do...
Sintered metal is a material created by heating metal powder particles below their melting point, causing them to bond together and form a solid object with a desired shape, essentially "sintering" the powder into a solid piece through the application of heat and pressure; this process allows fo...
I am waiting for some memory to be delivered then will be starting my build for the first time and would like to know what temps at idle and gaming must get to be too hot.The processor will have a Noctua NH D15 on top of it and I have a choice of thermal compounds the Noctu...
As a general rule, the larger a fish is, the more likely it is to eatotherfish for food—which increases the amount of mercury it contains. Avoid fish like swordfish, tilefish, and king mackerel, sticking to smaller fish like cod, tilapia, shrimp, andsalmon. ...
to energy transport. As the atmosphere thins, it is in ever reducing contact within itself, so energy transfer will increasingly be by radiation, which is measured as a flux of electromagnetic energy. This happens at the top of the lower atmosphere, below 0.1Bar, in the tropopause. This ...
This process of electrochemically destroying the dielectric layer results in higher-than-specified leakage currents, which are exacerbated as the thinning dielectric layer begins to break down under the stress of the application voltage. Since leakage current results in internal heating and increases in ...
Low unemployment is not considered healthy, as lower rates can be seen as inflationary due to pricing pressure on salaries; however, high unemployment is not considered healthy, as higher rates can be seen as a financial strain on consumer spending. In general, most experts deem unemployment betw...
