_Q_means the heat absorbed, _m_ is the mass of the substance absorbing heat, _c_ is the specific heat capacity and ∆_T_is the change in temperature. The First Law of Thermodynamics and Heat The first law of thermodynamics states that the change in internal energy of a substance is ...
The specific heat capacity (c) of a substance is the amount of energy needed to change the temperature of 1 kg of the substance by 1 unit of temperature. Different substances have different specific heat capacities, for example, water has a specific heat capacity of 4,181 joules/kg degrees ...

The energy used to heat a substance can be calculated using the formula: Q = mcΔT, where Q is the heat energy in joules, m is the mass of the substance in kilograms, c is the specific heat capacity of the substance (J/kg·°C), and ΔT is the change in temperature in ...
Finally, g is for the stated amount of the substance.What Is the Molar Heat Capacity of Water? Remember, the molar heat capacity of a substance is the heat capacity of 1 mol of a substance. This means that in the units you should include mol instead of grams. Instead of grams, you ...
In review, specific heat capacity is the amount of energy needed to change the temperature of a substance. Now, in this context, heat is sometimes referred to as heat energy, and it's the total energy contained within a substance. Energy is simply the ability to do work. Heat energy, ...
