Determine the change in the internal energy of helium, in kj/kg, as it undergoes a change of state from 100 kpa and 20°c to 600 kpa and 300°c using the equation of state p(ν - a) = rt where a = 0.01 m3/kg, and compare the result to the value obtained by using the ideal gas equation of state.

the answer is learned

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
