Warm, humid air facilitates smells by allowing scent molecules to move more freely through the air while also heightening our nose’s ability to detect those smells lingering in the air. Content continues below Cold and dry weather, on the other hand, work...
Why do gas molecules enter liquids? Do they enter solids? Why do liquids take the shape of their container? Why do gases condense when they are cooled? Why do liquids flow? Why are liquids usually difficult to compress? Explain why water vapor turns into a liquid as it cools. ...
What happens to the volume of air as it rises? What happens to its temperature? What happens when iron reacts with steam? What happens when sunlight hits greenhouse gas molecules? What happens when lightning strikes water? Explain why water vapor turns into a liquid as it cools. How does w...
Boilingbegins near the source of heat. When the pan bottom becomes hot enough, H2O molecules begin to break their bonds to their fellow molecules, turning from sloshy liquid to wispy gas. The result: hot pockets of water vapor, the long-awaited, boiling-up bubbles. Does boiling water always...
As the ice melts,the orderly arrangement collapses and the water molecules move past each other and actually get closer together as liquid water. ... As energy is transferred to the water molecules in the ice, the motion of the molecules increases. ...
The main area we’re losing eyes on is the stratosphere, the all-important home of the ozone layer. Across the stratosphere’s cold, thin air, ozone molecules are constantly being formed and destroyed, tossed and swept, as they interact with other gases. Some of these gases ha...
All you need to understand, for example, a perfectly diffused gas enclosed in a box, is its volume, temperature and the total number of gas molecules. But many natural phenomena – from earthquakes and air turbulence to rapid cooling or climate change – occur when things are far from ...
He has led me in the dark from my bedroom down the long steep stairs, through the long narrow living room, around the corner to the cold dark Kitchen where with trembling hands I turn on the stove and fill the saucepan with cold leftover coffee… watching the blue flames light up the ...
Currents just move the heat, they neither create or destroy it. Theoretically yes seas can become hotter if the cold water is removed; on a side note, the reverse process happens when the faster molecules are removed by evaporation, the water cools down. Jan 27, 2007...
Expiratory-reserve volume is the volume of air expired in forceful expiration from lungs. In normal conditions when there is not any exercising the volume of air during a breath is tidal volume. But after tidal volume, the volume of air that is expired forci...
