Question

Water has a maximum density at _____ degree centigrade.

(a) 32

(b) 100

(c) 0

(d) 4

This question was posed to me in unit test.

The question is from Hydrogen in chapter Hydrogen of Chemistry – Class 11

Answer 1

Right answer is (d) 4

Best explanation: Water has a maximum density at 4-degree centigrade, this is because at 4-degree centigrade, as opposite forces are in balance that is like the formation of Ice and maintaining of the liquid phase of water. Any less than 4-degree centigrade or greater than 4-degree centigrade, the water density is lesser than that of 4-degree centigrade.
