## Carnot´s ideal engine

The educational resource shows an interactive animation about the Carnot's engine: it is a theoretical model, not a real one, but we can already see in it the fundamental characteristics of real heat ...

## Thermal equilibrium

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 tem ...

## The heating curve

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 te ...

## Temperature scales

The educational resource shows an interactive animation about tempereture scales: there are various ways of expressing what the temperature of a body is. Each system is known as a temperature scale.

## Perpetual motion

The educational resource shows an interactive animation about the perpetual motion: Is it possible to construct a system that moves indefinitely without having to supply any energy? If such a system w ...

## The first law of thermodynamics

The educational resource shows an interactive animation about the first law of thermodynamics:when we heat a pressure cooker, the heat we supply to the water is used to increase the temperature of the ...

## Heat

The educational resource shows an interactive animation about the heat: heat is the transference of energy from one body to another in such a way that the internal energies of both are modified. If th ...

## The mechanical equivalent of heat

The educational resource shows an interactive animation about the mechanical equivalent of heat: if energy is measured in Joules and heat is a form of energy, what is the relation between Joules and c ...

## The second law of thermodynamics

The educational resource shows an interactive animation about the second law of thermodynamics for heat engines: it is not possible to achieve perpetual motion based on continuous reciprocal conversio ...

## The thermometer

The educational resource shows an interactive animation about the thermometer: the fact that mercury and alcohol expand when the temperature increases is used to construct thermometers. If we fix the ...
