Change of phase

The educational resource shows an interactive animation about the change of phase: solids melt when they are heated and liquids evaporate, changing to a gaseous state. If you increase the vibration of ...

Equilibrium between different states

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) w ...

Latent heat

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. This energy does not contr ...

Specific heat

The educational resource shows an interactive animation about the specific heat concept: when a body is heated, the temperature it finally reaches depends on the nature of the body. This property is k ...

Changes of state

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.

Joule´s experiment

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 insid ...

Changes in water

The educational resource shows an interactive animation about changes in water: the change from a solid to a liquid is called fusion. The change from a liquid to a gas is called evaporation. When wate ...

The internal combustion engine

The educational resource shows an interactive animation about the internal combustion engine: in real combustion engines, the energy is extracted from the combustion of some type of fuel, which has be ...
