Question 1 Report
lf the temperature of a small quantity of water in a closed container is gradually increased from 0o to 40oC then the density of the water within this range
The density of water decreases as its temperature increases from 0oC to 4oC, after which it increases. Therefore, as the temperature of the small quantity of water in a closed container is gradually increased from 0oC to 40oC, its density will first decrease until it reaches a minimum value at 4oC, and then it will increase. Therefore, the correct answer is (A) "increases for a while and then decreases".
