Answer:
If I fill a measuring cylinder to exactly 1,000 mL with water at 4.0°C , and I then reduce the temperature of the measuring cylinder and water to 2°C, will the water level in the cylinder rise above the 1000 mL line - or drop below the 1000 mL line?
Water is at its maximum density at 4.0°C . This means that if you increase the temperature - OR decrease the temperature of the water - the density will drop. Because the mass remains constant , the volume of the water must increase if the density reduces.
The conclusion therefore is that at 2°C the level of the water in the measuring cylinder wil
