Thermal equilibrium with measureAPP

Principle

Why do tea or coffee get cold onstanding, but never hot? The students watch, the water temperatures when a vessel containing cold water is dipped into a hot water bath.

Benefits

Thermal equilibrium with SMARTsense

Dilatation des métaux

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 ...

We 3.2 Coefficient de conduction de chaleur de métaux

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 ...

We 3.5 Absorption du rayonnement thermique

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 ...

Thermal insulation avec measureAPP

A quick loss of heat is sometimes not wanted. What can be done to keep the temperature in a vessel
constant? Students are measuring the cooling of hot water in two different environments.

Thermal insulation avec SMARTsense

Heating of water

Principle

How depends the time required to heat up water on the amount of water when a defined heating source is available? The students are heating up various amounts of water with an electric heating coil and measure the time dependence of the ...

Heating of water with SMARTsense

Heating of various liquids avec measureAPP

Principle

Do different liquids heat up to the same extent when subject to the same heating? The students are heating 100 g and 100 ml of water and of glycerol with an electric heating coil and measure the temperature in dependence on 

Principe de l'expérience

Une quantité mesurée d'eau est chauffée avec un bobine en déterminant la production d'énergie électrique. A partir de l'augmentation de la température et de l'énergie thermique, ...
