#### Online heat conversion tool

① After a certain process temperature changes to △ t, it absorbs (or emits) heat. Q represents heat (J)

Q=c·m·Δt．

Q suck=c·m·（t－t0）

Q put=c·m·（t0－t）

(T0 is the initial temperature; t is the last temperature)

Where C is the specific heat (capacity) associated with this process.

The unit of heat is the same as the unit of work and energy. The unit of heat in the International System of Units is Joule (abbreviated as Joke, abbreviated as J) (standing in honor of the scientist Joule). The caloric unit has been defined in history as calories (abbreviated as cal, abbreviated as cal), which is only used as an auxiliary unit of energy, 1 cal = 4.184 joules.

` Note: 1 kcal = 1000 calories = 1000 calories = 4184 joules = 4.184 kJ `

``` The equilibrium relationship between the amount of heat absorbed and the amount of heat released and stored in a certain period of time. △T=（t1-t0） ②Calculation formula of heat released by complete combustion of solid fuel: Q release = mq Calculation formula of heat released by complete combustion of gaseous fuel: Q = Vq The mass of the fuel (kg), V represents the volume of the gaseous fuel (m ^ 3). q = Q put / m (solid); q = Q put / v (gas) W = Q put = qm = Q put / m W = Q put = qV = Q put / v (W: total work) (The heating value is related to the pressure) SI system international unit: Q ———— The heat released after a certain fuel is completely burned ———— J m ———— represents the mass of a certain fuel ———— kg q ———— The calorific value of a certain fuel ———— J / kg Thermal energy calculation formula Q=△t*m*C (Specific heat capacity is C, mass is m, Δt is temperature difference) ```
