Percepción del calor

Principle

In this experiment the students should determine that the heat sensitivity of their skin does not allow a reliable estimation of the temperature. Its estimate is, on the contrary, dependent on which temperature was available previously for comparison.

Benefits

  • Real stand ...

Equilibrio térmico

Principle

When two bodies with different temperatures contact each other, a process of temperature equalisation takes place until both bodies have the same temperature (thermal equilibrium). The students should measure the temporal course of the temperatures of such two bodies ...

Calibración de un termómetro (modelo de termómetro)

Principle

The Celsius temperature scale is defined by the melting and boiling points of water. The students should calibrate a non-graduated thermometer and then make a few measurements with it.

Medición de temperatura con termocupla

Principle

If two different metals are in contact, a contact potential results from the different electron affinity of the metals' surfaces. The size of this potential is a function of the temperature since the electron's kinetic energy increases with increasing temperature.
These ...

Coeficiente de dilatación de líquidos

Principle

Using water as a model the expansion of a liquid is shown as a function of temperature. In the supplementary problem, the expansion coefficient is calculated at different temperatures. The expansion of water is not linear; its coefficient is not constant.
If you wish to ...

Dilatación del aire a presión constante

Principle

Heating a volume of air can lead to both an increase in volume and an increase in pressure. In this experiment the pressure must remain constant. This is achieved by ensuring that the water level in both manometer limbs is the same before reading the ...

Dilatación del aire a volumen constante

Principle

Heating a volume of air can lead to both an increase in volume and an increase in pressure. In this experiment the volume must be kept constant. This is achieved by marking the initial water level in limb a of the manometer and resetting the water level to this ...

Dilatación longitudinal de metales

Principle

Metal tubes are heated with steam. The linear expansion of three different metals is determined with the aid of a rotating-shaft pointer. From this the metals' coefficient of linear expansion is determined (Supplementary problem). The use of a rolling-shaft pointer is ...

Bimetal

Principle

To understand this experiment the students must be familiar with the linear expansion of metals. In experiment 1 the bending of a bimetal strip during heating is shown. In experiment 2a switch is constructed with the bimetal strip.

Bimetal

Principle

In order to be able to understand this experiment, the students must know about the linear expansion of solid objects due to heating. This experiment demonstrates the deformation of a bimetal following the application of heat.

Benefits

  • Experiment guides are very easy to ...

Coeficiente de conducción de calor de metales

Principle

One end of a U-shaped metal rod is immersed in boiling water and the other in cold water. From the warming of the cold water qualitative and quantitative statements can be made about the influence of the rod's composition, length and diameter on the heat flow through it. Since ...

Corrientes térmicas en líquidos y gases

Principle

The students should recognize that heating of liquids or gases causes a current since the heated medium has a lower density than the cold one and, thus, rises.
In closed systems this leads to circulation. The current transports heat energy.

Conducción de calor en líquidos

Principle

This experiment shows vividly that water is a poor conductor of heat: while the water at the top is boiling, the piece of ice normally does not melt quickly. A heat flow does not occur since the water is heated at the top.
