So you can place the liquid in a container with standardized markings. Volume can change based on temperature and pressure though. The SI unit of volume is the cubic meter. Other units used can be cubic centimeters, liters, etc. Often we choose the units based on the situation. To use units in an equation though, it's often better to start with SI units. You can convert between units of volume using ratios.
So the syllogism is valid. For a syllogism to be valid, the combined diagram must contain all the information asserted by the conclusion. It may contain more information, but it cannot omit anything. Now let's try a syllogism with a particular premise. Example:
This is a false assumption. The W3C HTML Validator checks for validity from an SGML point of view, but there are some well-formedness rules which it does not check. With a basic understanding of validity and well-formedness, it is easy to see why a document may be well-formed yet not valid.ust because an XHTML document is well-formed doesn't mean it's valid, and despite popular assumption, just because an XHTML document is valid (according to the classic definition used by the current W3C Validator) doesn't mean it's well-formed.
