Question

At 4 °C, the density of water is .
(a) 10 g/cm3
(b) 4 g/cm3
(c) 4 x 10³ kg/m3
(d) 1 x 10³ kg/m3​

Answer 1

Answer:

answer 4

Explanation:

density of water is maximum at 4°c which is 1×10^3kg/m^3

Answer 2

(d) 1 x 10³ kg/m3​

Explanation:

The density will be less than 1g/cm³ when the temperature varies by more than or even less than 4 degrees. Only pure water has a density of 1 grams per square millimeter.

The water molecules vibrate and the density rises when the temp of warm water drops. Clusters begin to develop at 4 °C. The atoms still are slowing down and getting closer together, while cluster formation causes them to be wider apart, resulting in a maximum density of water at 4 °C.
