小学四年级 · P4⚡ Energy
Follow heat as it flows from hot to cold — faster through some materials than others — and see how gaining or losing heat changes things.
你将学到
- Heat always flows from a hotter object to a cooler one, until both are the same temperature
- Heat flows quickly through good conductors (metals) and slowly through poor conductors (wood, plastic, air, rubber)
- Gaining heat makes matter expand; losing heat makes it contract
- Heat gain or loss can change the state of matter — melting, boiling, evaporating, condensing, freezing
