Answer: The beaker in which water level has decreased more is the one that contains pure water.
Explanation: Even when water is not heated it can evaporate, that is because molecules move at different speed and those that are closer to surface can break the gass pressure and scape as water vapor.
The movement of molecules of water can be affected by the presence of solutes (salts or other soluble compounds) and increase the evaporation temperature. For this particular case, molecules of salt atract the water molecules (remember salt has ions and water is a dipole with partial charges) and do not let the water move freely which avoid them to scape to the surface.
No, isotopes would have a different number of electrons
Answer:
kinetic energy is directly proportional to the absolute temperature this is because when absolute temperature is increased it tends to cause more collision of the particles which hence increases kinetic energy of the particles .
since kinetic energy is the energy due to motion
