① After a certain process, the temperature changes to △t, and it absorbs (or releases) heat. Q represents heat (J)
Q=c·m·Δt．
Q suction=c·m·（t－t0）
Q put=c·m·（t0－t）
(t0 is the initial temperature; t is the final temperature)
Where C is the specific heat (capacity) associated with this process.
The units of heat are the same as those of work and energy. The unit of heat in the International System of Units is Joule (abbreviated as Joule, abbreviated as J) (erected in memory of the scientist Joule). Historically, the unit of heat has been defined as calorie (abbreviated as cal), which is only used as an auxiliary unit of energy, 1 calorie = 4.184 joules.
Note: 1 kcal = 1000 calories = 1000 calories = 4184 joules = 4.184
kilojoules
The balanced relationship between the heat absorbed and the heat released and stored in a certain area within a certain period of time.
△T=（t1-t0）
②固体燃料完全燃烧释放的热量的计算公式：Q放=mq 气体燃料完全燃烧释放的热量的计算公式：Q=Vq Q表示热量(J)，q表示热值( J/kg )，m表示固体燃料的质量(kg)，V表示气体燃料的体积(m^3）。
q=Q release/m (solid); q=Q release/v (gas)
W=Q discharge=qm=Q discharge/m W=Q discharge=qV=Q discharge/v (W: total power)
(Calorific value is related to pressure)
SI international units:
Q————The heat released after complete combustion of a certain fuel——Joule J
m————indicates the mass of a certain fuel——kilogram kg
q——indicates the calorific value of a certain fuel——joules per kilogram J/kg
Thermal energy calculation formula
Q=△t*m*C
(Specific heat capacity is C, mass is m, Δt is the temperature difference)
