_______ _______ explains why matter
expands when heated and contracts when
cooled.
Thermal expansionThermal expansion
Why is it easier to remove a tight jar lid by running hot water over it than by prying it off with a knife?
The hot jar lid has The hot jar lid has caused the metal to caused the metal to
expand so it is not as expand so it is not as tight on the glass jartight on the glass jar
