Woolen clothes keep the body warm because of:
Correct answer: A. Bad conductivity
- A. Bad conductivity
- B. Good conductivity
- C. Low temperature
- D. None of these options are correct
Explanation
Since air is a bad conductor of heat, it prevents the loss of heat from the body, thus keeping it warm. The wool in itself is a bad conductor of heat, does not allow heat generated by the body to escape, and insulates the body well.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
