Q indicates the heat (J).
Q=c·m·Δt．
Q Suck = c.m. (t-t0)
Q drop=c m (t0-t)
(t0 is first temperature;t is last temperature)
C is the heat associated with the process.
The units of heat are the same as the units of power and energy. The units of heat in international units are joules (column, abbreviated by J) (to commemorate the scientist joules).
Note: 1 kilocalorie = 1,000 calories = 4,184 joules = 4.184 kilojoules.
The balance between the amount of heat absorbed within a given period of time and the amount of heat released, stored.
△T=（t1-t0）
A formula for calculating the amount of heat released from full combustion of 2 solid fuels: Q release = mq gas fuel total combustion of heat: Q = Vq Q indicates the amount of heat (J), q indicates the value of heat (J/kg), m indicates the quality of solid fuel (kg) and V indicates the volume of gas fuel (m) 3.
q = Q release/m (solid); q = Q release/v (gas)
W =Q drop = Q drop/m W = Q drop/v
(Thermal value is related to pressure)
SI international unit:
Q----The heat released by the full combustion of a certain fuel--Journ--Journ--
m-- represents the mass of a fuel - kg
q--- which indicates the heat of a fuel--Journ/kg J/kg
Thermal formula
Q=△t*m*C
(C, mass m, t, temperature difference)
