Specific heat is the amount of heat required to raise one gram of any substance one degree Celsius or Kelvin. The formula for specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.
Using specific heat to predict the amount of heat absorbed or released in reactions. Heat Capacity and Specific Heat
This chemistry tutorial covers the difference between heat capacity and specific heat and includes several examples of how to find specific heat and how to use specific heat in calculations. Bomb Calorimeter
A bomb calorimeter is used for measuring energy released in a combustion reaction. This reaction takes place in a water bath, so that the water absorbs the energy released and we can measure how much its temperature rises accordingly.
Understanding how to measure the heat from a chemical reaction using a bomb calorimeter. Bomb Calorimetry
This video shows how a bomb calorimeter can be set up and operated.
Enthalpy
Enthalpy is the heat content of a system at constant pressure, but chemists almost always talk about change in enthalpy rather than total energy. Endothermic reactions have positive changes in enthalpy while exothermic reactions have negative changes in enthalpy.
Understanding the concept of enthalpy. Enthalpy - Thermodynamics
Understanding why enthalpy can be viewed as "heat content" in a constant pressure system. Thermochemical Equations
Thermochemical equations are balanced chemical equations that include the physical states of all reactants and products and the energy change. If energy is a reactant, the reaction is endothermic but if energy is a product, the reaction is exothermic.
Understanding and solving thermochemical equations. Thermochemical Equations Practice Problems
How much heat gets released or absorbed in a chemical reaction? We'll learn how to calculate this. We will use molar mass and conversion factors to figure out the enthalpy change in exothermic and endothermic reactions, which are represented by thermochemical equations.
