How does the water cycle purify water?
How does the water cycle purify water? The water used by plants can go back into the earth by transpiration. The evaporation and condensation are the key terms that help water purifying. While these processes occur during the water cycle, it can also be used to purify water for drinking or industry use. Water is […]

How do you deal with low voltage?
How do you deal with low voltage? Use the next-highest setting above the battery’s voltage. Press the test leads against the battery terminals (you don’t have to match the test leads to specific terminals). A low voltage indicates that the battery is probably shot. Take the tool, battery, and charger to a service center. How […]

What is the Kelvin Planck statement of the second law?
What is the Kelvin Planck statement of the second law? The Kelvin–Planck statement (or the Heat Engine Statement) of the second law of thermodynamics states that it is impossible to devise a cyclically operating heat engine, the effect of which is to absorb energy in the form of heat from a single thermal reservoir and […]
What is domain ferromagnetism?
What is domain ferromagnetism? In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. Their atomic makeup is such that smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. What is […]
