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.
You can make a solid dissolve faster in water that; 1. Stirring the mixture, the solid dissolves faster, that doesn't effect amount of resolition 2.he warmer the water, the faster the water molecules move, thus enabling them to pull apart the solid faster. 2. Stirring the mixture (this gets more of the water in contact with the solid, faster). 3. If it's not already done, breaking the solid up into smaller particles.
