Calidad del auga - contaminación con metales pesados

Principle

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanicor similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may be ...

Calidad del auga - contaminación con metales pesados con Display Connect

Principle

Demonstration experiment using wireless data transmission to a large digital to display. Heavy metal ions can seep into water courses, for example from galvanising plants or other similar industries. They have the effect of suppressing the action of enzymes, so that the ...

Aislamiento térmico con Cobra4

Principle

A quick loss of heat is sometimes not wanted. What can be done to keep the temperature in a vessel
constant?

Tasks

Measure the cooling of hot water in two different environments:

  • In a glass beaker that is fitted out with thermal insulation in the form of felt sheets ...

Calentamiento de diferentes líquidos con Cobra4

Principle

Do different liquids heat up to the same extent when subject to the same heating?

Tasks

Heat 100 g and 100 ml of water and of glycerol with an electric heating coil and measure the temperature
in dependence on time.

Capacidad calorífica específica del agua con Cobra4

Principle

In households, a great amount of energy is used to heat up water - for showers, for washing clothes, for cooking. Exactly how much is necessary for each degree that each mililitre of water is warmed up? How are amount of heat, heat capacity and change in ...

Calor de mezclas y capacidad calorífica de un calorímetro con Cobra4

Principle

Quantities of heat distribute themselves so that finally all parts that are in contact with each other have the same temperature. If the heat capacities and the initial temperatures are known, then the final temperature can be predicted. Or, in reverse, the final temperature can ...

Capacidad calorífica de metales con Cobra4

Principle

The calorimeter can be used to determinethe heat content of a piece of metal.The heat content can be calculated fromthe mixing temperature that is reachedin the calorimeter.

Tasks

Heat up metal bodies of the same mass but different metals to the same temperature in a water ...

Medición calorimétrica de temperatura con Cobra4

Principle

Calorimetry can also be used to determine the temperature of a hot object that is difficult to measured by any other method, e.g. because it is too hot for the thermometers available. The heatcontent of the object can be calculated from the mixture temperature that is reached in ...

Conversión de energía mecánica en energía interna con Cobra4

Principle

Different forms of energy can be converted into each other. Here the potential energy of steel pellets is converted to heat when falling pellets collide.

Tasks

Let the pellets drop the same distance numerous times and measure how quickly they warm up.

Curvas de fusión y solidificación de tiosulfato de sodio con Cobra4

Principle

How does a temperature curve express the change of state of a substance that occurs when it is heated or cooled?

Tasks

Heat sodium thiosulphate until it melts and let it cool down again. Measure the behaviour of the temperature
in dependence on time under uniform heat input ...

Evaporación con Cobra4

Principle

Drinks can be cooled by putting the bottle in a moist sock and letting the sock dry. The same process occurs when our bodies are cooled by sweating. The change in temperature that occurs is to be examined in this experiment.

Tasks

Wet the absorbent paper with water or ...

Movimiento uniformemente acelerado en un plano inclinado s ~ t² con Cobra4

Principle

A body experiences uniform accelerated motion on an inclined plane due to the gravitational forces exerted on it. The motion of the cart is in a straight line and characterized by a temporally constant change in speed.

Conservación del impulso en la colisión elástica central con Cobra4

Principle

An impulse is a change in momentum caused by a force F in a short amount of time. The momentum p is defined here as the product of force F and time t and is conserved if no friction loss occurs and the collision is elastic. This means that in a closed system of different bodies ...
