Equilibrio térmico con 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

·         Especially ...

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 ...

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 ...

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 ...

Aislamiento térmico con 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.

Calentamiendo del agua con measureAPP

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 ...

Calentamiento de diferentes líquidos con 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         Especially understandable and didactic prepared experiment descriptions including protocol
