The volume of water he dissolved the solute is 250 cubic centimeter.
<u>Explanation</u>:
Concentration = mass of solute in g / volume in dm^3
The concentration of a solution is defined as the ratio of mass of solute in grams to the volume of water in dm^3.
If concentration of a solution = 8 g/dm^3.
mass of solute =2 g.
Volume of a water = 2 / 8 = 0.25 dm^3. (or) 250 cubic centimeter.

Answer:
chemical changes that happen when food goes bad. All food will eventually rot if not eaten, but keeping the food cold slows the rotting process. Chemical changes are affected by temperature. More heat or energy (a higher temperature) usually allows for faster chemical changes.
