# Melting, freezing and boiling, sentence 3

<!-- .ven lang=en -->
When water vapour in the air touches something cold, like a chilled can or a winter window, it turns back into droplets; the water came from the air, not through the can.

<!-- .vintro -->
**Who acts:** water vapour, it, water · **What happens:** touch, chill, turn back, come · **To what, where:** something, droplets, air

<!-- .vabout -->
This is a sentence of the lesson «Melting, freezing and boiling» of the physics course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (water vapour, it, water), what happens, when and where, as Mova's frames read it from the tree.

**The tree:** Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R7-rel-agree ×1. **The frames** are read from the tree by Mova's frames reader (`prag`) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
