The educational resource shows an interactive animation about the thermal equilibrium: when two substances at different temperatures are in contact, they exchange a certain amount of energy. One's temperature increases, and the other's decreaeses. In the end, they both reach the same temperature, which is known as equilibrium temperature.

The educational resource shows an interactive animation about the heating curve: when a body is heated, its temperature increases until there is a change of state; while the change takes place, the temperature remains constant.

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.

In this teaching unit you will learn: To understand the concept of a simple machine as an instrument which saves effort but not work. To understand the way in which energy from wind or water is converted into the mechanical energy of a circular movement. To assimilate the equivalence between mechanical energy and heat.   To formulate the first and second law of thermodynamics in a simple way. To learn to use the mathematical formulae for these laws to make simple predictions about the working...
