Ali puts a metal spoon and a wooden spoon into the same cup of hot water. After a minute, the handle of the metal spoon feels hotter. Why?
Metal is a good conductor of heat. Heat travels from the hot water through the metal spoon to its handle faster than through the wooden spoon.
Key idea: heat flows from a hotter place to a colder one; metals let it flow quickly.
Use the key words: gains heat, good conductor of heat.
Understand the idea, then explain it in your own words.
