The opposite of definite in volume (solids and liquids) would be indefinite in volume, as in gases, which can vary in volume for a given mass (pressure).

Solids have definite shape and definite volume. Liquids have not definite shape but have definite volume. Gases have neither definite shape not definite volume.
WATER has no definite shape but has definite volume.
WATER has no definite shape but has definite volume.
