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.
Best Answer: The attractions that the polar water molecules have for the individual ions are stronger than the attractions the ions have for each other. As a result, the water molecules pull the ions apart. Higher temperature typically makes ionic compounds dissolve more and faster.This is due to: a) the particles move faster at higher temperature b) the water molecules spread out slightly providing more space to hold ions.Source(s):hen an ionic compound is dissolved in water it will conduct electricity better. Increasing the temperature of the water allows this process to happen quicker while decreasing the temperature causes the process to slow. One source to use is listed below:
