The specific heat of a substance can be used to calculate the temperature change that a given substance will undergo when it is either heated or cooled. The equation that relates heat (q) (q) to specific heat (cp) (c p), mass (m) (m), and temperature change (ΔT) (Δ T) is shown below. q = cp × m × ΔT q = c p × m × Δ T.

13 Δεκ 2023 · The chemical equation for this reaction is as follows: \[Cu_{(s)} + 4HNO_{3(aq)} \rightarrow Cu(NO_3)_{2(aq)} + 2H_2O_{(l)} + 2NO_{2(g)} \label{5.4.1}\] If the reaction is carried out in a closed system that is maintained at constant pressure by a movable piston, the piston will rise as nitrogen dioxide gas is formed (Figure (\PageIndex{1}\)).
6 Μαρ 2024 · Heat Formula Using Heat Capacity. One method of calculating the amount of heat transfer to or from a substance is using its heat capacity. Heat capacity is the amount of heat required to change the temperature of a certain quantity of the substance by one degree. The equation is: Q=mcΔT. Where: Q is the heat added or removed, m is the mass of ...
14 Αυγ 2020 · In order the calculate heat energy changes you need to know the mass of the substance being heated, the temperature change and the specific heat capacity of the substance. The specific heat capacity, c is the energy needed to raise the temperature of 1 g of a substance by 1 °C.
