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 controlle ...
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 ...
The ideal gas equation describes the thermal state of an enclosed gas with regard to the parameters of state; pressure p, volume V, temperature T and number of gas molecules n. It enables three different gas laws to be derived, each for the behaviour ...
The ideal gas law describes the thermal state of the gas enclosed in a vessel relative to the properties pressure p, volume V, temperature T, and amount of substance n. It can be used to derive three different laws which describe how a gas behav ...
The general gas equation describes the relationship between pressure, volume and temperature of an enclosed gas volume. A gas syringe is used for measuring the relationship between the volume and the pressure, which is sealed with the help of motor oi ...
The characteristic curve of current against voltage of an electrolytic bath containing copper sulphate solution and having copper electrodes is measured. Visible changes in the electrodes and the bath are observed.
The electrical conductivity is not only dependent on the type and concentration of the electrolytes, but also on other parameters of state. For example, increasing temperature is mostly accompanied by an increase in conductivity, which can be attributed to the expon ...
This experiment shows how much the quality of drinking water of various locations in the same region can vary. The comparison of tap water with bottled mineral water and distilled water leads to surprising results.
Measure the characteristic curve of current against voltage of an electrolytic bath containing copper sulphate solution and having copper electrodes. Observe visible changes in the electrodes and the bath.
