How does conduction worrk?
Conduction can only occur in solids. Good conductors are metal, for example. In conduction, there is a heat source. The heat will heat up one part of the solid. As a result, the particles vibrate voilently. Then, the vibrating particles will make particles next to them vibrate and so on...
Are Atoms easily destroyed when matter is cooled or heated?
atoms cannot be created or destroyed...in easy words, heating something up only gives it kinetic energy because of which its molecules start vibrating...
What is heat on a molecular level?
Heat is not a molecule, it's a form of energy. It is conducted from molecule to molecule in conduction and convection (not in heating by radiation). Molecules with high kinetic energy give their energy to molecules with low kinetic energy , that's how heat is conducted.
Why does furnace heat only part of the house?
You need a furnace expert to come and inspect it and tell you the answer.
All molecular motion ceases at 0 Kelvin why?
All molecular motion stops at absolute zero because absolute zero is the coldest possible temperature. And it is only able to achieve this temperature if the molecules/atom do not possess any thermal energy. And thermal energy is what causes vibrating motion of the molecules/atom. Thus at this temperature no molecules/atoms will vibrate due to the complete lack of energy.
What are molecules always doing?
Molecules in a solid are constantly vibrating. Heating a solid increases the vibration of the molecules. Solids stay fixed because of the attraction between their molecules. This can be broken by increasing heat and therefore vibration to the point of inducing a phase change.
What ubstance in the food absorbs the microwaves?
Water molecules in the food. Microwaves work by only vibrating the water molecules, in order to increase the temperature of the food without significantly altering the properties of the food itself.
What is the basic theory of heat transfer?
Heat transfer occurs by convection, conduction and radiation. In conduction, heat is transferred through collision of rapidly moving molecules. It is only through successive collision of molecules that heat transfers through an object.
How is sound energy is formed?
sound energy is formed by a vibrating body. We can say that sound is produced only when a body is vibrating.
Does heat move only where atoms and molecules are?
No. There is empty space between the sun and earth, but radiant heat gets through that empty region.
Does hot water and cold water have the same molecular structure?
Yes, the only difference is that hot water's atoms are vibrating faster and therefore producing more heat.
Can you get vibrating on your iPod Touch?
No. No software update or hardware will enable vibrating. This feature is available only with iPhone.
What state is the matter in when all molecules are just vibrating around?
All forms except a Bose-Einstein condensate, which only occurs at absolute zero.

How does it help a cell by only letting certain molecules pas through?
it can keep the cell from dying if if the wrong molecules come through
Does a lighter object have fewer molecules?
Only if it is of the same material. In other cases, it may, or may not, have less molecules. Molecules come in many different sizes (or masses).
