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.

10: Convert 77.0 L at 18.0 mmHg to its new volume at standard pressure.
olchik [2.2K]

Answer:

The answer to your question is   V2 = 1.82 l

Explanation:

Data

Volume 1 = 77 l

Pressure 1 = 18 mmHg

Volume 2 = ?

Pressure 2 = 760 mmHg

Process

Use Boyle's law to solve this problem

                P1V1 = P2V2

-Solve for V2

                 V2 = P1V1/P2

-Substitution

                 V2 = (18 x 77) / 760

-Simplification

                 V2 = 1386 / 760

-Result

                 V2 = 1.82 l
