# What is everything made of?, sentence 18

<!-- .ven lang=en -->
When ice melts, the same water molecules (a molecule = a small group of atoms joined together) are there before and after; melted ice weighs the same as the ice did.

<!-- .vintro -->
**Who acts:** ice, same water molecules, melted ice · **What happens:** melt, join, be, weigh · **To what, where:** atoms, same

<!-- .vabout -->
This is a sentence of the lesson «What is everything made of?» of the chemistry 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 (ice, same water molecules, melted ice), 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): R2-punct-next ×1, R7-rel-agree ×1, R8-pos-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.
