Question 1 Report

lf the temperature of a small quantity of water in a closed container is gradually increased from 0^o to 40^oC then the density of the water within this range

increases for a while and then decreases

decreases for a while and then increases

increases gradually

decreases gradually

remains the same

Answer Details

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