Change the narration: You said to me, "Water freezes at 0°C".
Change the narration: You said to me, "Water freezes at 0°C".
Explanation
"You told me that water freezes at 0°C."
The original sentence is a statement of a general/scientific fact ("Water freezes at 0°C").
In reported speech:
- "Said to" changes to "told" (more natural for reported speech)
- The tense remains present ("freezes") because it's a universal truth
- The conjunction "that" is properly used
- The factual information remains unchanged
