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.
Increasing the temperature of a solvent speeds up the movement of its particles. This increase cause more solvent particles to bump into the solute. As a result, solute partic â¦ les break loose and dissolve faster. Temperature often affects solubility rates. Endothermic stuff tends  to go faster in warm, and exothermic stuff tends to go faster in  cool. + 126 others found this useful.
