10) In the winter, people like to wear coats. Why is this?

1. Coats increase the temperature of cold air through convection.
2. Coats decrease the loss of body heat to surroundings through insulation.
3. Coats increase the amount of heat generated by the body through conduction.
4. Coats generate heat energy through solar power.
5. Coats transform cold wind energy into thermal energy.

Coats provide insulation by reducing the amount of heat lost from the body.
