Hess’ Law of Heat Summation Hess’ Law states that: "The enthalpy change for any reaction depends on the products and reactants and is independent of the pathway or the number of steps between the reactant and product". BASICALLY: Hess’ Law states "the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps" >This is also known as the "law of constant heat summation". All it means is that no matter how many steps the chemical

Heat‚ Temperature‚ and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water‚ while it was boiling in a kettle‚ as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change‚ the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly

3 Methods of Heat Transfer Now in Physics we learn that there are three methods of heat transfer‚ this being: Radiation‚ Conduction‚ and Convection. Let’s start with radiation; radiation is the transfer of energy as electromagnetic waves. So basically it does not need to directly touch anything or move any particles around‚ much like convection and conduction do. Radiation mostly occurs through empty space‚ so I think a good example of radiation would be when you feel warm in front of a fire
