Morphology
liquid + nitrogen
The phrase is a straightforward adjective+noun composition: 'liquid' specifies the physical state of 'nitrogen', so the meaning 'nitrogen in liquid form' is directly derivable from the constituents. Although it's a technical term, the pattern is common across languages and follows normal English composition, so a B1 learner who knows both words would understand it.
Etymology
Liquid nitrogen names the element nitrogen after it has been turned into a liquid by very low temperatures. Imagine a gas made into a pool so cold it freezes things on touch; that's why 'liquid nitrogen' means nitrogen in a very cold liquid form and is used to freeze or chill items.
