Weight is a measure of how much gravity pulls on a mass or object. On the moon, there is less gravity pulling on objects, so they weigh less. ... Remember, even if you weigh less because of a change in gravity's force on your body, your body's mass is still the same.
The melting point would decrease
Answer:
An atom is composed of a positively-charged nucleus, with a cloud of negatively-charged electrons surrounding it, bound together by electrostatic force. ... Protons and neutrons are bound together to form a nucleus by the nuclear force.
The correct answer is the second option. These deposits are a result of solutes becoming un-dissolved from a solution. These solutes are from the water or liquid that you are boiling in the kettle. As you boil a liquid mixture, it is possible that some of the solutes would precipitate because the solubility of such solute is lowered due to the increase in the temperature. Most solubility of solid solutes are related to temperature inversely. So, as the temperature increases, the solubility would decrease. Solubility is the amount of a solute that can be completely dissolved in a certain amount of solvent.
