When we press down on a syringe full of air, the pressure increases. Why did it increase when there has been no temperature change? How is the speed of molecules of air affected when the air rapidly expands? Why adiabatic expansion produces cooling? Explain why air moving over an object ...
A hot air balloon rises when it is heated because the heat increases the kinetic energy of the molecules in the balloon and this leads to the air...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
This random movement is what we in the biz’ call “heat energy”. Heat is literally just the random motion of atoms. When an air molecule is close to the ground it’s moving pretty fast, but if it has a chance to bounce higher, then it will slow down during the trip. W...
As the warm air rises it expands and cools. Since cool air cannot hold as much moisture this often results in rainfall. The cooled air is then drawn back towards the poles, sinking towards the earth to replace the air moving along the surface towards the equator. This cycle of air movemen...
a hot object, the caloric in the hot object will spread out to the cold object until they reach the same temperature. When air expands, the caloric is spread out more thinly, thus the temperature drops. When air is compressed there is more caloric per volume, and the temperature rises. ...
During the day, air above the land heats up faster than air over water.Warm air over land expands and rises, and heavier, cooler air rushes into take its place, creating wind. What instrument measures vibration? Depending on the quantity measured, a vibration measuring instrument is calleda ...
If ETH rises 10% on the same day, Molly’s profit will be 2500*10%-25-2.5=$222.5. If ETH falls 10% on the same day, Molly loses only $25 in position fees and $2.5 in transaction fees. This is addressing a whole new demand for trading – a market that has always...
So, should you consider value for money when buying your next watch? Check out our article on what makes a good watch! It would help if you focused on the overall delivery of the watch instead of paying more for it. The watch looks good online, but it may not be enjoyable in the ac...
When the earth surface gets heated up, it heats the air above it. As this hot air comes in contact with any water body, it heats up the water which vaporizes and as the air rises with the water vapor, the latter cools down and forms clouds. As the clouds raise further up, their si...
Whether we’re staring into the depths of a campfire or watching a Space Shuttle burn 500,000 gallons of fuel as it rises off the launchpad, mankind’s obsession with fire is so innate we almost take it for granted. Yet fire has catalyzed the human race’s most significant innovations;...
