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: Heat provides energy for the water molecules to move about more rapidly. As a result, many of the molecular bonds present in the liquid (water) are broken. These broken bonds result in molecules being spaced out which forms a gas. In the case of water, this gas is what we know as steam. That's the chemical side of it (sort of). As for what would visibly happen when water is heated, it depends on the temperature. The water would boil at 100 degrees celsius which would lead to bubbling and evaporation. Steam is formed.
