The calculating formula of heat

                                                      The calculating formula of heat

(1) through a process of temperature change as the delta t, it absorbs heat (or release). Q said heat (J),

Q = c m. Δ t.
Q = c m. absorption (t - t0)
Q = c m. (t0)
(t0 is the initial temperature; T is at the end of the temperature)
Which is associated with the process of specific heat C (let).
The unit of heat is the same as the unit of work and energy. Unit is the joule heat in the international system of units (hereinafter referred to as focal, abbreviated as J) (joule stand in memory of scientists). Historically defined thermal units for calories (hereinafter referred to as card, abbreviated as CAL), only as an aid in the unit of energy, 1 card = 4.184.
Note: 1 kcal = 1000 = 1000 = 4184 joule = 4184 calories
An area in a certain period of time to absorb and release heat, storing heat to maintain the equilibrium relationship.
Delta T = (t1 - t0)
(2) the calculation formula of solid fuel combustion heat release: put the Q = mq gas fuel combustion heat release calculation formula of: Q = VqQ said heat (J), Q means calorific value (J/kg), m said the quality of the solid fuel (kg), V said the volume of a gas fuel (m ^ 3).
Q = q/m (solid); Q = q/v (gas)
W = Q feed = qm = Q/m W = Q feed = qV = Q/v (W: total energy)
(about) calorific value and pressure
SI international units:
Q - some kind of fuel combustion after release of heat - joule J
M - said some kind of fuel quality - kg kg
Q - said some fuel calorific value - joule per kilogram of J/kg
Thermal calculation formula

(specific heat C, the quality is m, Δ t is the temperature difference)
