heat

heat in physics, is energy which is spontaneously flowing from an object with a high temperature to an object with a lower temperature.

• The unit of heat is calori, in SI is joule.
• Definiton of one calorie the amount of heat energy to raise the temperature of 1 degree celsius of 1 gram of water.

1 calori = 4, 2 Joule

1 Joule = 0, 24 calori

The quantity of heat transferred to a matter is depand on :

1. mass of an object

2. spesific heat of matter

3. temperatur of matter

Mathematical formula :

Q = m. c. ΔT

m =Mass (Kg)

c = Spesific heat of matter (joue/kg0 C)

ΔT = Change of temperature (0C)

Q = Quantity of heat (Joule)
