On a cold night, Sherrie sits on her couch wrapped in a blanket. Which best describes the blanket?

• The blanket is a conductor because it allows the heat to get from the air to Sherrie.

• The blanket is an insulator because it prevents Sherrie's body heat from flowing into the air around her.

• The blanket is an insulator because it prevents the cold air around Sherrie from getting to her.

• The blanket is a conductor because it allows the cold air around Sherrie to get to her.
