HEAT TRANSFER'S |
calorimeter to measure the heat |
You definitely have to make hot tea or coffee or even like. when you're holding a glass of hot tea or warm milk is what you feel is hot. why is that???
it can happen because of the heat that is in a glass of warm water such that its temperature higher temperatures move into his hands lower. so that heat is the transfer of energy from a high temperature to a lower temperature object. while the unit itself is the Joule heat.
water heated on the stove |
have you boil water in a pot and heating it on the stove???
Why do you heat the water may boil??
it is because the heat is on the burner switch to the pan and then move on to the water so that the water can boil. naaaaah its now the question is how heat can move??? Heat can be transferred in three ways: conduction, convection and radiation.
HEAT TRANSFER'S
1. In Conduction Heat Transfer of
heat transfer by conduction is the transfer of heat to a substance without being followed by the displacement of molecules - molecules her. this is why the pot shaft is made of an insulating material such as plastic or wood. because the material is an insulator does not easily conduct heat to heat food or water.
2. In Convection Heat Transfer of
heat transfer by convection is kebalin of heat transfer is conduction heat transfer to an object or substance followed by molecule - the molecule. examples such as onshore wind and sea're trying.
examples of heat transfer by radiation |
3. In Heat Transfer of Radiation
The radiation heat transfer is heat transfer that does not require intermediaries. for example as the heat of the sun to the earth. heat until hot sun can not deliver conduction or convection. because the air is the conductor of the worst and also between the sun and the earth there is a vacuum that can not conduct heat.
example from transfer's haet |
and many more examples - another example of heat transfer. may be useful yaaaa ^ _ ^
