Kalor

Heat is a form of energy that moves from a high temperature to low temperature. If an object receiving / releasing heat so the temperature it will go up / down or changing the form of objects.

SOME DEFINITIONS Heat

1 calorie is the heat required to raise the temperature of 1 gram of water by 1 º C.

1 calorie = 4.18 joules
1 joule = 0.24 calories
Heat capacity (H)

is the amount of heat required by the substance to raise its temperature 1 º C (units of calories / º C).


Heat of the type (c) is the amount of heat required to raise 1 gram or 1 kg of a substance by 1 º C (units of calories / gram. º C or kcal / kg º C).



Heat used to raise / lower the temperature without changing states of matter:

Q = H. dt
Q = m. c. dt
H = m. c

Q = the heat off / accepted
H = heat capacity
Dt = increase / decrease in temperature
m = mass of the object
c = heat type

Heat absorbed / released (Q) in the process of changing the form of objects:

Q = m. L

m = mass of object kg
L = latent heat (heat of melting, heat frozen. Heat of steam, heat moisture, heat sublime, heat disappears) ® t / kg

So the heat is absorbed (â) or released (á) in the event of changes in the form of objects do not cause changes in body temperature (body temperature constant).
