Absorción de radiación térmica

Principle

A polished and a black beaker are heated by radiation. Instead of solar radiation a bright flame located in front of the two beakers is used.
Both beakers are filled with air since the heat capacity of water is very large and it would be too slowly heated.

Benefits

  • Real ...

Calentamiento de distintos volúmenes del agua

Principle

Different quantities of water are heated with a heating coil in a calorimeter. The quantities of water were chosen to match the size of the calorimeter (100 ml, 150 ml, 200 ml) and are directly related to each other so that the following becomes obvious:
the greater the quantity ...

Calentamiento de diferentes líquidos

Principle

The dependence of heating a liquid on its specific heat capacity should be established in this experiment. In these experiments, the liquids' masses and their thermal input are the same. Thus, the specific heat capacities obtained are not absolute, but can be given in ...

Capacidad calorífica específica del agua

Principle

A measured quantity of water is heated with a heating coil. The electrical heat output is determined. From the temperature increase and the heat energy, the specific heat capacity of water is calculated. This calculation is performed under point 6 of "Evaluation", i.e. ...

Temperatura de mezclas

Principle

Different amounts of hot and cold water are mixed. The hot water is always poured into a calorimeter containing cold water (room temperature). This has the following advantage: the cold water defines the temperature of the calorimeter; and since the hot water is poured in, the ...

Capacidad calorífica de un calorímetro

Principle

The same quantities of hot and cold water are mixed. The hot water is always poured into a calorimeter containing cold water (room temperature). The measurements are repeated three times and the calorimeter's heat capacity is then calculated as the average value of the three ...

Capacidad calorífica específica de sólidos

Principle

Three metal bodies having the same mass are heated in boiling water and then successively placed in a calorimeter. Even from just the measured mix temperatures it is possible to make qualitative conclusions as to the size of the storage ability (heat capacity) of the metals. The ...

Curvas de fusión y solidificación de tiosulfato de sodio

Principle

The course of sodium thiosulfate's temperature during melting and subsequent freezing is measured. Moreover, it can be clearly seen that heat is necessary for the melting process: the temperature does not rise until all the salt has melted. During freezing this energy is ...

Calor específico de fusión de hielo

Principle

Ice cubes are placed in warm water and the specific heat of fusion of water is determined from the mix temperature. In relation, the calculations carried out in the evaluation show which mix temperature would occur in an experiment with the same volume of water at 0 °C. ...

Calor de evaporación del agua

Principle

To begin with, the course of the water's temperature during heating is measured so that the burner's thermal output can be determined. From this the quantity of energy required to vaporise a specific quantity of water can be calculated.

Calor de condensación del agua

Principle

Water vapour is conducted into a calorimeter containing cold water. From the mix temperature and the mass increase of the cold water, the specific heat of condensation of water is calculated. It is as large as the specific heat of vaporisation of water; i.e. the heat required ...
