The formula for specific heat capacity, C, of a substance with mass m, is C = Q /(m × ΔT). Where Q is the energy added and ΔT is the change in temperature.
Specific Heat Formula. As we discussed above the specific heat is the relation of temperature change of an object with water. Also, the formula is like this: Heat energy = (mass of the object or substance) × (specific heat) × (Change in temperature) Q = m × c × ΔT. Or. Q = mcΔT. Derivation of Specific Heat Formula.
The specific heat can be calculated from the amount of heat transferred into and out of a substance. The heat transfer equation provides a quantitative relationship between heat transfer, substance’s mass, specific heat, and temperature change.
The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC. The specific heat c is a property of the substance; its SI unit is J/ (kg⋅K) or J/ (kg⋅C). Recall that the temperature change (ΔT) is the same in units of kelvin and degrees Celsius.
Once you become familiar with the terms used for calculating specific heat, you should learn the equation for finding the specific heat of a substance. The formula is: C p = Q/mΔT. You can manipulate this formula if you want to find the change in the amount of heat instead of the specific heat.
Learning Objectives. Define heat capacity and specific heat capacity and differentiate between the two terms. Deduce which substance will have greatest temperature changed based on specific heat capacities. Calculate unknown variables based on known variables using the specific heat equation.
Specific heat is the quantity of heat essential to raise the temperature of one gram of any substance by 1 degree Celsius. Specific Heat formula is articulated as \(\begin{array}{l}C\;=\;\frac{\Delta Q}{m\;\Delta T}\end{array} \)
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.
