When a small stone is dropped into a pond of still water what happens? When that pebble is dropped in the pond, it pushes water out of the way. The water has nowhere to go but to the side and up, creating a circular peak around the drop point. This peak falls again, under the […]
What is the actual weight of molecule of water?
What is the actual weight of molecule of water? Therefore, 18g of mass of water is occupied by 6.022×1023 number of molecules. Therefore, we can calculate the mass of one molecule of water by dividing the mass of one mole of water and Avogadro number. The actual weight of a molecule of water is calculated […]
How gravity affects the movement of object?
How gravity affects the movement of object? On Earth, gravity pulls all objects to Earth’s center. Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the […]

Which liquid would evaporate most quickly at room temperature?
Which liquid would evaporate most quickly at room temperature? Acetone has the weakest intermolecular forces, so it evaporated most quickly. Water had the strongest intermolecular forces and evaporated most slowly. Which type of liquid dries the fastest? The rubbing alcohol evaporated the fastest followed by water and finally vinegar. Olive oil didn#t seem to evaporate […]
What is the mass of one electron in grams?
What is the mass of one electron in grams? The invariant mass of an electron is approximately 9.109×10−31 kilograms, or 5.489×10−4 atomic mass units. On the basis of Einstein’s principle of mass–energy equivalence, this mass corresponds to a rest energy of 0.511 MeV. The ratio between the mass of a proton and that of an […]
