how is heat transferred between two objects?

Question

please help me with my homework!?!?

Answer 1

Conduction, I do believe

Answer 2

All of these answers are correct in some sense. Heat is just a form of energy and heat transfer is merely energy transfer. This can be done through friction (like sandpaper on wood), radiation (the sun's solar radiance on the Earth), convection (which is like friction of air passing across a surface), chemical interactions often have excess energy which is release in the form of heat or radiation.

Answer 3

There are several ways of heat transfer. Direct flame contact. Radiation like the suns heat. Convection, hot air. Conduction, like a hot pan touching food.

Answer 4

the transfer of heat is in three types.
>1:conduction
>2:convection
>3:radiaton

In conduction,when a body is started to heat up,it's atoms start to thrilling and vibrating.due to vibrating,one atom strikes with another one,and during this process,some of heat energy is transfered to the other atom.and thus gradually,all the atoms in body are heated.and finally,the whole body is heated up.this is only applicable for those objects which contain valance electrons.

In convection,when a liquid is started to heat up,it's molecules
start motion which is called moleculer motion because of heat.when the lower side molecules of the container are heated up,they become light and thus go to upper side,and the upper side molecules come down.this process is continued untill whole molecules are heated up.
this process is only applicable for liquids.

In radiation,heat is directoly transferred through space and requires no medium.

Answer 5

Radiation, Conduction, or Convection.

Answer 6

By conduction,convection and radiation

Answer 7

If the two or the two products are changing their state--melting, boiling..--their temperatures are consistent. in the event that they are no longer changing their state, then their temperature could desire to alter. answer is c)

Answer 8

friction
