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...
