Question

Which of these would have the lowest kinetic energy?

boiling water
ice water
refrigerated water
water at room temperature

Answer 1

Answer: ice water

Step-by-step explanation: Kinetic energy is the energy possessed by a substance by virtue of its motion and is directly proportional to the temperature of substance.

`K.E=(3)/(2)RT`

R= gas constant

T= temperature

Thus boiling water will have a temperature of around
`100^0C`, ice water will have a temperature of
`0^0C`, refrigerated water will have a temperature of more than
`0^0C`, 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.

Answer 2

The answer is ice water, since the particles of a solid have very low kinetic energy.
