Thermal conduction



Principle

Energy can be transmitted through heat convection, heat radiation or heat conduction. The greater the thermal conductivity of a wall, the higher the temperature of its exterior. This property is used to compare the temperatures and thus the thermal conductivity of ...

Influence of surface on the absorption of solar energy

 Principle

In this experiment a white tent in the desert will be simulated by means of a white absorber plate which is exposed under a halogen lamp for 5 minutes. The temperature difference before and after the irradiation is compared to that of a black absorber plate. The outcome ...

Influence of insulation on the absorption of solar energy



Principle

The temperature increase is much higher in the case of the insulated plate as opposed to the uncovered plate. When the plate is not insulated, it can lose heat energy to air flowing by and through the radiation of heat.

Benefits

  • Experiment is part of a ...

Using the greenhouse effect with a solar collector



Principle

The greenhouse effect in the solar collector works not only for the better heat insulation of the solar collector, but also for its protection from the external influences of the weather. The heating is not significantly influenced by the plexiglass disc, but ...

Thermal radiation and greenhouse effect



Principle

This experiment explains the principle of the greenhouse effect. At a surface temperature of about 5600°C, the sun mainly irradiates heat radiation in an area of 500 nm in the direction of the Earth direction. The terrestrial atmosphere allows the radiation of ...

Influence of number of rotor blades

Principle

From their environment, students usually know of wind turbines that have 3 blades. There are also models with only 2 blades or with completely different structures. In contrast, water wheels have more blades ("Blätter"), and they are suitable for driving large machinery. In ...
