IdkAnswer:
Explanation: idk am sorry
This question is basically asking us to convert the volume from mL to kL.
We can do this by setting up a multiplication problem and cancelling out units:

So now we know that
the Bay water will occupy 1.25x10^-4 kL.
Answer:
pH solutions cause the water to become more basic or more acidic therefore would force the organisms to adapt to their new situations
For your first question, that equation only works if your situation is occurring at a constant temperature. Your original question is such a situation - everything occurs at 298.15 K. Therefore, you can use this value in the equation to calculate work.
For your second question, Charles' Law describes how the volume of gas changes as you heat or cool it, PROVIDED PRESSURE AND MOLES OF GAS REMAIN CONSTANT THE WHOLE TIME. In your original question above, temperature stays constant while volume changes. However, what they don't tell you is that this necessarily requires a change in either pressure or moles of gas. Because the question works with the same sample the of gas the whole time (i.e. moles are constant), it is pressure that is changing (and this change will occur according to Boyle's Law, since temperature and moles are held constant).
Hope that clarifies things!
