What holds heat longer soil or sand?

Sand because molecules stay heated within.


After a mixture of iron and sulfur are heated and then cooled a magnet no longer attracts the iron How would you classify the resulting material?

A chemical reaction has ocurred her and it has now formed a compund.


Why does calcium carbonate lose mass if heated?

Limestone loses mass when heated because of a chemical change: the gas carbon dioxide (CO2) is released by a chemical process when the rock is heated. The heat turns some of the calcium carbonate of the limestone into calcium oxide (quicklime) and carbon dioxide.


What is a sulfur well?

A sulphur well is where super heated steam is pumped into an underground sulphur deposit. The sulphur then liquifies and is then pumped to surface. This method is no longer employed since the introduction of low sulphur fuels. More than enough sulphur is removed from crude oil to meet world demand.


Why does heated air rise?

Substances that have internal movement(gas, liquid, and solids to a certain degree) will have convection currents. The concept is most easily understood in a gas. As gases are heated their molecules travels faster and faster. The faster they move and the more the kinetic energy involved in the collisions causes the gas to increase in volume. This means that the particles are further apart and therefore the density of the gas decreases. And substances with lower density will rise. This can also be thought of as kinetic and potential energies. As the gas is heated the molecules inside have increased kinetic energy. The increased energy of the molecules allows the molecule to reach higher potential energy levels(which means the molecule can rise). jacquie s has a science test tomorow Hope that helps.

If a pot is no longer heated when will the convection currents stop flowing?

the currents would stop as soon as the heated substace has cold completely.


What happends to convection currents when the liquid or gas is no longer heated?

What happens to convection currents when the liquid or gas is no longer heat?

Nothing actually happens to convection currents when heat is no longer supplied. The currents are produced by applying heat, most often to the bottom. The warmed fluid is 'lighter' than the cold fluid surrounding so it rises to allow colder fluid to replace it and be heated. As soon as the heat is removed, all the fluid rapidly comes to a single temperature and convevtion does not happen! An opposite effect happens when cold air sits on the surface of a lake. In this case the water at the surface cools, gets 'heavier' and sinks. In this case the convection currents operates downwards.

What happens to convections currents when the liguid or gas is no longer heated?

The conventional currents will continue until the temperature of the substance is equal to surrounding temp.


Why does the closed lid of thermal mug keeps liquid hotter for longer?

so that the heated particles cannot escape-convection :)


What does the high specific heat of water have to do with the convection currents in the air at the seashore?

Water'specific heat capacity is 4200 J/Kg°C . This high specific heat capacity suggests that the water will travel long distances without losing heat . This makes the convection currents in the air last longer.


Why does the Pangaea supercontinent no longer exist?

The Pangaea super-continent no longer exists because it has broken up into the continents that exist today, as a result of continental drift caused by convection currents in the earth's mantle.


What happens to an enzyme when it is heated?

When an enzyme is heated it is denatured, which means that it can no longer function.


How do convection radiators work?

Being designed to radiate (give out/emit etc) the thermal energy of the hot water inside them, a convection radiator will heat the air above itself. As the gas is heated it expands (thermal energy is "converted" to kinetic energy and hence the molecules move faster and hence expand), as the gas expands it's density decreases and so it rises above the cooler, denser gas surrounding it. As more gas is heated the gas will diffuse across the roof of the room and gradually cool. When the gas is initially heated it's original volume is filled by in-rushing cooler gas, this in turn is heated, eventually the original gas, which has recently cooled and descended, is heated once more thus forming a convection current. One of the problems with convection heating of any kind is the tendency for the central areas of large spaces to remain unheated, furthermore longer spaces may not be heated at the far end from the heat source as the gas cools and descends before travelling the length of the space.

Does it take longer to saturate a heated solution than a cold solution?

No, a heated solution will saturate faster.
