A student heats a metal ball and a wooden ball of the same size to the same high temperature. She then places each ball on a block of ice.
The metal ball melts more ice than the wooden ball. Which statement best explains this?
The metal ball melts more ice than the wooden ball. Which statement best explains this?
- Metal conducts heat better, so it transfers more heat to the ice.
- Metal has a lower temperature, so it cools the ice faster.
- Wood is a better conductor, so it keeps the ice from melting.
- Wood radiates more heat away to the air instead of to the ice.
