Aditya is using two thin blankets instead of one thick blanket in winter to keep himself warm because the air trapped between the blankets is a poor conductor of heat. This concept can be explained with the principles of thermal insulation:
- Heat transfer in solids, liquids, and gases occurs through conduction, convection, and radiation. Of these, conduction is the primary mode of heat transfer in solids.
- When Aditya uses two thin blankets, there is a layer of air trapped between them.
- Air is a gas, and gases are generally poor conductors of heat. This is because gas molecules are spaced far apart, reducing the frequency of collisions that facilitate heat transfer.
- The trapped air acts as an insulating layer, reducing heat loss from Aditya's body to the colder external environment.
Thus, Aditya stays warmer using two thin blankets due to the ineffective heat conduction of the trapped air, maintaining body warmth more efficiently.
