When water at 4°C is heated, it expands. When water at 4°C is cooled, it

1) contracts, 2) expands, 3) neither contracts nor expands, 4) not enough information given, which follows from the fact that 5) cooling decreases the kinetic energy of H2O molecules. 6) water has its greatest density at 4°C. 7) we do not know how the water is cooled.
