Question

The density of water at 4o C is
  1. minimum
  2. maximum
  3. 103Kg/m3
  4. 1Kg/m3

A
minimum
B
maximum
C
103Kg/m3
D
1Kg/m3
Solution
Verified by Toppr

Water has its maximum density of 1g/cm3 or 1000kg/m3 at 4C. When the temperature changes from either greater or less than 4 degrees, the density will become less than 1g/cm3. Water has the maximum density of 1g/cm3 only when it is pure water.
