How do I effectively stop heat from transferring between two bodies of matter?

whoissarthak's idea works, but that isn't a wet suit; that's a dry suit.  A wet suit works differently.  The idea is that there are basically three ways to move heat: conduction, radiation, and convection.  Conduction is when two things are in direct contact, like touching a hot stove or a cold flagpole.  Radiation has to do with the infrared light emited by warm bodies, and has nothing much to do with your project.  Convection is the real concern--it is the transfer of heat by means of a fluid intermediate, and it is the fast form of heat loss.\n\nYou're body sheds heat by means of perspiration, where sweat evaporates and takes heat away with it--that's convection.  When you fell colder in a strong breexe, that's convection taking heat away quicker.  When you blow on a spoon of hot soup to cool it, that's convection.\n\nThe way a wetsuit works is by not allowing the water in contact with the skin to be carried away.  It inhibits the movement of water through it.  Enough gets in to contact the skin and make your skin wet, which is why they call it a wetsuit, but that water doesn't leave easily.  It stays put and your body heats up the water.  Hence, the water in your wetsuit is much warmer than the water in the surrounding ocean, so the water taking heat from your skin is not quickly carried away and replaced by more cold water.\n\nIf you want to make a wetsuit, you want something htat will make it difficult (but not impossible) for water to come and go.

I don't really understand what your question is.  In the first place, heat always flows from a warmer object to a cooler one.  That maximizes the number of possible arrangements of energy quanta, leading to an increased entropy.

There are three ways that thermal energy can be transmitted. (1) By radiation of photons. The photons are absorbed by materials and transfer their kinetic energy to the materials. (2) By convection in liquids and gases. The molecules of the fluid have kinetic energy depending upon their temperature. This energy of motion is transferred  to adjacent molecules.  Also as fluids heat up their density decreases and they rise against gravity in a motion called convection.  (3) By conduction in materials.  As the molecules of the material heat up, their kinetic energy of motion is transferred to adjacent molecules by collision.

Each material has a property known as "thermal conductivity" its  how easily or hard for heat can travel through a material. Heat will travel faster on materials with high or good thermal conductivity such as aluminum or copper and not as fast on material such as ceramics or bricks with low or poor thermal conductivity. \n\nThis has something to do with their atomic structure and bond strength between atoms. Think of atoms attached together with springs. When heat is introduced, atoms will start vibrating and its energy (from the heat) will "bounce" or shake its neighboring atoms and shake its other neighbor and so on... until every atom are shaking like crazy because they are transferring heat to the rest of the material.  Some takes more heat (or energy) to disturb the atomic structure of a material and heat doesn't travel or conduct "well" thru it. I hope this makes sense...

Bernoulli's principle can be tried.\nLaws of forces can be demonstrated.\nThermodynamics-transfer of heat.....etc

decrease potential energy.....through physical factors like friction....

No you can not. THe air particles would desolve it way faster. THere is no way to preserve it.

Heat is simply a form of energy.  If there are two objects at the same temperature then no energy (heat) will be exchanged.  If there is a temperature difference then energy will transfer via one or more methods (convection, conduction, radiation...) until the temperatures of the two objects are equal.  \n\nThis is only a very simple conceptual definition but I hope it helps.  I can go into far more detail but then it gets complicated.

You have the potential for galvanic corrosion.  Essentially, two metals at different potentials share electrons and one metal (the one with the higher potential) will start to erode and "plate" the other metal.\n\nTypically, using some sort of material that is a non-conductor (ceramics, rubber, etc) between the two or passivating the metal surfaces or coating the metal surfaces (prime and paint per ANSI standards) are your best options to prevent this.

Well that's a good one though, I suppose you can't do that. What you think is simple is too complicated. We have a lot of problems maintaining the  temperature as a constant. You simply cant stabilize it. It will keep oscillating. You can still do it, but they'll be expensive and hard. It all depends on the surrounding temperature, where you put it, what the jugs are made up of(material) and so on.  But, you can maintain the temperature within a certain range. Contact your thermodynamics teacher for assistance.

They may call it friction but it's a misnomer.  There is skin friction, of course, which dissipates energy as heat, but much of the drag force is caused by imparting kinetic energy to the air mass, i.e., shoving it out of the way.  If you were shoving all the air downward that force would be called lift.  That energy may eventually be dissipated but it is theoretically recoverable. Friction dissipates energy as heat immediately.

heat losses can be caused by one of three mechanisms:  conduction, convection, and radiation.\n\ngenerally heat moves from a warmer body to a colder body.  this is especially true for conduction and convection, and in most instances, radiation as well.\n\nconduction implies there is some medium around the body to carry heat away from it to possibly another body.  your comparison to osmosis is somewhat analogous.  recall, osmosis concerns liquid solutions passing through a pourous membrane.  here the concentration is somewhat like the heat, but not exactly.\n\nconvection implies a fluid is being used to transfer heat away from the warm body. convection can be free or forced (think a cooling fan).\n\nradiation is the way heat is transferred via electromagnetics.  this is how the heat of the sun reaches the earth in the vacuum of space.

Use the ideal gas law \n\nPV/T = constant for the final and initial states.

This is a bit complicated but you might try this....\n\nStart with a centralized heat source, preferably electrical, so it should remain fairly constant.  You will need three thermometers, each to be held in place by their own stands.  Place a block or bar of metal so that it does not quite touch the heat source, and in contact with its thermometer at the far end.  Place a wooden bowl with water (a metal or glass container would taint your study ) near the heat source with its thermometer just in the water.  Place your last thermometer the same distance from the heat source, thus testing the heat conductivity of air.  If you had access to more thermometers and stands, you could place them at various points in a line from the heat source.  You will notice that the last thermometer will by far have the lowest readings.

To keep it simple, temperature doesn't travel only heat travels. It does so by conduction, convection or radiation.

Does it have to be a material? the best solution for this would be to have 2 cans one just inside the other with a compleat vacume between them, as there is no air to transmit the heat between them the liquid inside wont change tempreture.\n\nthis is the principle of a thermos flask,\n\nif you need an actual material, somthing that would trap air to stop it from moving and spreading the heat such as glass fiber like you might have in your loft\n\nhope this helps

Heat is absorbed by the particles of the substance causing their motion to increase.  As the motion of the particles increases they are able to break the forces of attraction holding them together and the move further apart.  So solids lose their regular pattern and become liquids; liquids break their attractions holding them together as a liquid and the particles move very far apart and become gases
