Assertion: On heating, a solid usually change to a liquid and the liquid on further heating change to the gaseous state. Reason : Arrangement of constituent particles is different in solid, liquid and gaseous state. AIf both assertion and reason are true and reason is the correct explanation ...
How drops of liquid move along parallel fibres in a perpendicular airflowDrops sitting on an array of parallel fibres spontaneously move along the fibres when subject to an airflow perpendicular to the array. The drops show long-range aerodynamic interactions with their downstream and upstream ...
Investors, then, will not have to give up unrealized gains for a quick sale. When thespreadbetween the bid and ask prices tightens,the market is more liquid; when it grows, the market instead becomes more illiquid. Markets for real estate are usually far less liquid than stock markets. The...
There are a few continental ridge areas, where the magma does spew out onto land; but most land volcanoes are produced by subduction zone volcanism and hot spot volcanism. When the solid rock changes form to a more liquid rock material, it becomes less dense than the surrounding solid rock....
Liquidity is how quickly an asset can be turned into cash. Monkey market accounts are liquid, whereas real estate is not. How Do I Get an Emergency Fund? Most emergency funds are build slowly, over many months or even years. To start one, open a high-yield savings account. You can do...
In addition, the same process of liquid and gas interacting in pore spaces also applies to the way freshwater aquifers get recharged by rainfall, as the water percolates into the ground and displaces air in the soil. A better understanding of this process could be important for management of ...
How Does Heat Move by Alicia Klepeis, Cavendish Square, 2019. This is a fairly solid introduction to conduction, convection, radiation, and the basics of kinetic theory for ages 8–10. Eyewitness Energy by Jack Challoner and Dan Green. Dorling Kindersley (DK), 2016. This covers the history...
That doesn’t work in a world where big moves are required to move up the Power Curve of performance. Take a look below at how well other companies are doing at adopting the changes I’ve described. Can you do better...
Inside the single tank, parts of the solid are kept at low to high temperatures, in a temperature gradient, depending on the flow of fluid. For storage purposes, hot heat-transfer fluid flows into the top of the tank and cools as it travels downward, exiting as a low temperature liquid....
The worst thing to do is to thrash around in the sand and move your arms and legs through the mixture. You will only succeed in forcing yourself farther down into the liquid sandpit. The best thing to do is to make slow movements and bring yourself to the surface, then just lie back....
