When we touch something we often say it is hot or cold. Obviously we are referring to some property that feels different with respect to our own body and we refer to this as energy. We have also noticed that we feel hotness when we are near fire or a light or from the sun. The characteristic of matter we are referring to is the energy that is contained and transmitted; Every object possesses internal thermal energy contained in an object and this depends on the amount of the substance.
