WebJan 7, 2024 · the magnitude of the temperature change (in this case, from 21 °C to 85 °C). The specific heat of water is 4.184 J/g °C (Table 12.3.1 ), so to heat 1 g of water by 1 °C requires 4.184 J. We note that since 4.184 J is required to heat 1 g of water by 1 °C, we will need 800 times as much to heat 800 g of water by 1 °C.

Enthalpy is a state function which means the energy change between two states is independent of the path. Since equation 1 and 2 add to become equation 3, we can say: ΔH3 = ΔH1 + ΔH2. god and circles

WebDec 23, 2024 · The specific heat capacity is the heat or energy required to change one unit mass of a substance of a constant volume by 1 °C. The formula is Cv = Q / (ΔT ⨉ m). What is the formula for specific heat? The formula for specific heat capacity, C, of a substance with mass m, is C = Q / (m ⨉ ΔT). WebThe heat change, q, in a reaction is given by the equation q = mcΔT; where m is the mass of the substance that has a temperature change ΔT and a specific heat capacity c.
