What are three factors that makes a rock susceptible to weathering?
Activities of living organisms (animal burrows, plant roots), Pressure from overlying load\materials and atmospheric conditions.
What are three units used to describe air pressure?
The SI unit is the pascal, equal to one newton per square meter. A bar is exactly 100,000 pascal. An atmosphere is approximately equal to a bar. Torr means more or less the same as mmHg, and refers to the pressure caused by a liquid column of mercury (Hg).
What are three factors or variables that affect the speed of sound?
Notice: The speed of sound changes with temperature and a little bit with humidity − but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading. The temperature indication, however, is absolutely necessary. The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.547 feet per second.
What four things affect pressure?
Change in volume - container getting bigger or smaller with same amount of air; Change in temperature - air gets hotter or colder causing it to expand or contract; Change in density - air is pumped into or out of a fixed container.
What common substance can be found in all three physical stateses under various atmospheric conditions?
This substance is water.
What causes the global winds to separate into three bands?
pressure gradient For A+ The earth's rotation
What does bar mean in chemistry?
"Bar" is approximately the pressure of earth's atmosphere at sea level. Multiple bars are multiple normal air pressures. Three bar is three times the air pressure at sea level, etc. Technically a bar is defined as 100 kPa, which is very slightly less than standard atmospheric pressure (1 atmosphere = 1.01325 bar).
What are three real examples of real world circular flow?
-- wind pattern around an atmospheric center of high pressure -- wind pattern around an atmospheric center of low pressure -- liquid running down the drain
What three things affect airpressure?
Heat, number of molecules, atmospheric pressure and volume Volume * Pressure = molecules * molar gas constant * Heat
What are three types of isolines?
Isobars - Measure atmospheric pressure Isotherms - Measure temperature Isoheights - Measure elevation
Weather is caused by variations in what three basic ingredients?
temperature, pressure, volume, and density temperature, pressure, volume, and density
Why in mountainous regions the boiling point of water don't reach 100 degree celsius?
That's because the pressure is lower than 1 ATM (StP at sea level).Remember that (like you state in your question): it is the boiling POINT of water: meaning TWO variables have a certain value, i.e. pressure AND temperature for ONE boiling point.Sohere are three boiling points of water as example: (approx. indicative T.p.-values)50oC at 0.1 ATM.100oC at 1.0 ATM.180oC at 10.0 ATM.
What is the atmospheric pressure if the partial pressure of nitrogen oxygen and argon are 442mm Hg 118.34mm Hg and 5.66mm Hg respectively?
These three components are the three largest components of air. The total pressure of a gas mixture is just the sum of the partial pressures of each component. Air is a mixture and nitrogen, oxygen, and argon are the three biggest components. So, the atmospheric pressure (or air pressure) would be the sum of the partial pressure of each component of the air: Ptot=PPnitrogen + PPoxygen+ PPargon = 442 mmHg + 118.34 mmHg + 5.66 mmHg = 566 mmHg
What does the rate of evaporation depend on?
The rate of evaporation relies on three main things. It varies according to the pressure, humidity and the atmospheric temperature.
What are three factors that makes a rock susceptible to weathering?
Activities of living organisms (animal burrows, plant roots), Pressure from overlying load\materials and atmospheric conditions.
What chilly solid changes directly to a gas at -78.5 celsius?
Frozen Carbon Dioxide also called dry ice. The behavior you describe happens only at pressure less than 5 times sea-level atmospheric pressure. Above that pressure, carbon dioxide has the familiar three states ... solid when it's chilly, liquid when it melts, and gas when it gets warm enough. The range of temperature across which it remains liquid depends on the pressure.
