The educational resource shows an interactive animation about the latent heat concept: the energy needed to produce a change of phase per unit mass is known as latent heat.

The educational resource shows an interactive animation about Joule´s experiment: the mechanical energy of a mass falling from a certain height can be transformed into an increase in temperature inside a liquid.

In this educational resource you can check the next physical phenomenon: when there is a change of state in pure substances, the temperature remains constant.

The educational resource shows an interactive animation about the equilibrium between different states: a substance (water, for example) in different states at different temperatures (ice and water) will eventually reach an equilibrium temperature.

The educational resource shows an interactive animation about the heat: heat is the transference of energy from one body to another.
