Is it true that certain materials exhibit negative thermal expansion and expand in response to cold temperatures?
Yes. Numerous scientific studies document negative thermal expansion (NTE) in various materials, proving that certain compounds contract upon heating and consequently expand in response to cold temperatures.
Verdict: SUPPORTED · 9 sources for, 0 against · Last checked
The analysis
The retrieved literature extensively discusses negative thermal expansion (NTE) materials, which contract upon heating and expand when cooled. Multiple studies across different material classes (frameworks, oxides, borates, carbon allotropes) consistently support the claim.
Evidence for · 9
Reviews various materials that exhibit negative thermal expansion (NTE), demonstrating that certain materials contract rather than expand under thermal changes.
