Question

Hot water _____. has a higher pH value than cold water holds less dissolved oxygen than cold water is beneficial to living organisms in aquatic ecosystems contains more hydrogen than cold water

Answer 1

Answer : The correct option is, Hot water holds less dissolved oxygen than cold water.

Explanation :

As we know that the gases are more soluble in the liquids at the lower temperatures.

When the water heats up the average kinetic energy of the molecule increases. That means at the higher temperature the more number of molecules will escape or evaporate in atmosphere.

But at lower temperature the less number of molecules will escape or evaporate in atmosphere.

Hence, the hot water holds less dissolved oxygen than cold water.

Answer 2

The correct answer is this one: "holds less dissolved oxygen than cold water" Hot water holds less dissolved oxygen than cold water. The hotter the water is, the lesser oxygen that is being dissolved in that water.
