The atmosphere is comprised of various gasses, including nitrogen, oxygen, and various trace gasses. These are comprised of molecules. These molecules move freely while exerting what's known as air pressure.Answer and Explanation: One atmosphere of pressure refers to one unit of atmospheric pressure...
STP is one atmosphere of pressure at 0 degrees C. Since this would be a freezing temperature at sea level, dry air is less dense than the cited value most of the time. However, air typically contains a lot of water vapor, which would make it denser than the cited value. The Density ...
What is the dew point when it rains? What is the air pressure in the thermosphere? What dew point temperature is considered tropical? Does the dew point change with altitude? What is one standard atmosphere of pressure in kilopascals?
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Standard temperature and pressure (STP) refers to the nominal conditions in the atmosphere at sea level. These conditions are 0 degrees Celsius and 1 atmosphere (atm) of pressure. The STP value is important to physicists, chemists, engineers, pilots and navigators, among others. ...
根据“Wind is caused by differences of pressure in the earth’s atmosphere.”和“When lots of these molecules move, usually in one direction, we call this wind.”和“For example, a southerly wind would blow from the south to the north.”和“Wind turbines and windfarms can generate ...
The units for vapor pressure :There are several units used for vapor pressure: Pascals (Pa), tor (mm Hg), atmospheres (atm) and bar (bar).The torr (symbol: Torr) is a unit of pressure, now defined as exactly 1⁄760 of a standard atmosphere. Thus one torr is exactly 101325⁄760...
[#insert1] Above this temperature, no matter what the atmospheric pressure, Venus’ oceans would have begun to evaporate, and the added water vapor in the atmosphere would have increased the greenhouse effect. [#insert2] This would have made the temperature even higher and caused the oceans ...
Now, as air is heated and becomes warmer, it expands, it becomes less dense. 现在,随着空气的加热和变暖,它膨胀起来,它变得稀薄。 When air in a particular area is heated, you get a concentration of warm air in an area of low pressure. ...
The pressure of one pascal is insufficient for describing pressures encountered in everyday life. Hence, its multiples, such as kilopascal kPaPa1kPa=103Pa and megapascal MPaPa1MPa=106Pa, are frequently employed. Another widely utilized unit of pressure is the standard atmosphere atmatm. PaMPakPa...
