Which of these observations are not explained by kinetic-molecular theory? X When a gas is heated, it expands.

o At very low temperatures, gases expand less for a given pressure change than they do at high

temperatures.

If the volume of a gas decreases, its pressure increases at constant temperature,

When gas is added to a rigid container, the pressure inside the container increases

At very low temperatures, gases expand less for a given pressure change than they do at high temperatures.

Explanation:

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
