This is a bit of a trick question! "Liquid" refers to the state of matter, not the volume.

Here's why it's tricky:

* Both 750mL and 1.5L are quantities of liquid. They describe the amount of a liquid, not its ability to flow.

* Liquids are generally considered "liquid" regardless of volume.

To answer your question directly, 1.5L contains more liquid than 750mL, but that doesn't make it *more* liquid.
