This girl is wearing pink wool earmuffs to keep her ears warm in the snowy weather. Differentiate between conductors and insulators. How does the wool affect heat transfer? (wool is a type of fabric)
The wool is a conductor that transfers heat from her ears to the wool earmuffs.
The wool is an insulator that provides heat to keep the girl's ears warm.
The wool is a conductor that transfers heat from the girl's earmuffs to her ears.
The wool is an insulator that keep the girl's ears from loosing heat.
