Answer: ice water
Explanation: Kinetic energy is the energy possessed by a substance by virtue of its motion and is directly proportional to the temperature of substance.
[tex]K.E=\frac{3}{2}RT[/tex]
R= gas constant
T= temperature
Thus boiling water will have a temperature of around [tex]100^0C[/tex], ice water will have a temperature of [tex]0^0C[/tex], refrigerated water will have a temperature of more than [tex]0^0C[/tex], and water at room temperature will have a temperature more than refrigerated water but less than boiling water.
Thus ice water has lowest temperature and thus will have lowest kinetic energy.
