Children, even those that are vaccinated, may develop rotavirus disease more than once. That is because neither natural infection with rotavirus nor rotavirus vaccination provides full immunity (protection) from future infections. Usually a personâs first infection with rotavirus causes the most severe symptoms.
Because molecules move quicker at higher temperature, causing them to collides more. Since they collides more, reaction occurs to be a lot faster to. And that's why things dissolve quicker in hot water than in room temperature water.
When water absorbs heat, it makes the individual water molecules vibrate faster. This is because heat is essentially evenly spread energy. If the molecules vibrate fast enough â¦ , they will be able to separate from each other and become a gas, which is what happens if the water evaporates and boils.hat happens to water molecules when water is heated? Like other molecules, water molecules, H2O (or H-O-H), move, vibrate and rotate in many ways at a temperature above absolute 0.
