Why would wearing several layers of clothing keep you warmer than wearing one heavy sweater?

• Layers of clothing trap layers air which act as an insulator.

• Layers of clothing trap layers of air which act as a conductor.

• The layers of clothing are thicker than the sweater.

• The layers of clothing allow the thermal energy to transfer through easily.
