What are the three mechanisms by which heat is transferred through the Earth's system?
convection (from the movement of fluids), conduction (through solids), and radiation (through air and space).
Why are solids and liquids condensed materials?
They are condensed materials because that's what makes them what they are. The more condensed a substance is the less it can flow. Gases are the least condensed, so they flow the easiest, followed by fluids, then solids.
Why can't solids flow?
the atoms and molecules are packed so close together there is no room for them to pass through each other
Why solids do not flow?
Solids do not flow because there is very little intermolecular space between them and hence they hold each other very tightly so they cannot flow
Substances that do not flow when poured?
solids i guess
Why solids are not called fluids?
Because the solid can be made to flow, or move so it is called as fluids
Can a solid flow?
yes indeed solids can flow as well. all states of matter are fluids.
Why does transfer of heat not take place in fluids?
Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.
Why are both liquids and solids called fluids?
Fluids are neither solids nor liquids. Fluids are a form between solids and liquids. Fluids donot exhibit a fixed shape like solids do and also are not free flowing as liquids are. Fluids, while maintaining their total volume can flow freely upto a certain extent. Though not very accurate, a fluid behaves some what like ketchup :)
Why do fluids liquids and gases flow?
because, unlike solids, they can't sustain shearing stress
Heat can travel by?
Heat can travel in 3 ways by conduction in solids, convection of fluids (liquids or gases), and radiation.
Why convection cannot take place in solids?
because the process requires the formation of currents which is only possible in fluids (i.e solids and liquids). It is not possible for currents to develop in solids for the simple reason that the molecules in a solid are not free to move around and they are contained in their fixed positions.
Is liquid water a fluid?
Any substance that can Flow is called a 'Fluid'. Water is a Fluid Liquid....It can Flow. Steam is a Fluid Gas...It can Flow. Therefore, Liquids and Gases are Fluids. (The Molecules of Solids are closely bonded and cannot move around and over each other. They vibrate in the same position...Solids therefore are not Fluids, they cannot flow). (Norrie wrote this not me so give credit to Norrie)
Do Solids usually conduct heat better then liquids and gases?
Solids do conduct heat better than gases, although not necessarily better than liquids. Some solids are actually composite materials, because they can have a porous structure which contains gas within the solid, and this results in solids that do not conduct heat very well. But it is the gas component which has this insulating property.
Why doesn't convection occur in a solid material?
Convection is fluid flow. It requires the movement of atoms and molecules within fluids (liquids or gases). In a solid, atoms and molecule are fixed in place and the material of a solid does not flow, so there can be no convection. Note 1. The answer above directly applies to 99.9% of the cases. There are peculiar amorphous materials, such as elastic materials, where one might consider them solid but they undergo some movement. There are also "visco-elastic" materials which exhibit both elasticity and flow. (For example below Earth's tectonic plates is the visco-elastic asthenosphere. Some artificial polymers and foams will behave partly as fluids and partly as elastic solids.) True solids do not flow. Note 2. There are links below related questions on why there is no heat transfer by convection in solids and why there is convection in fluids.
When Heat convection occurs in gases and liquids heat conviction does not occur in solids because solids are unable to?
..to flow as easily. A malleable (space between particles) structure is need for convection to take place.
What is the process to separate solids and fluids called?
One way to separate solids and fluids is through filtration. Pour the mixture through a filter and the solids will be trapped in the filter.
