Question:

Two shirts are warmer than a single shirt of double thickness . Why?

Heat Transfer

Heat transfer is a process in which heat energy gets transferred from one object to another, the three main ways of heat transfer are

  1. Heat Conduction: - A process that is more prominent in solids.
  2. Heat Convection: - A process that is more prominent if fluids like liquid or gases. and
  3. Heat Radiation: - A way of heat transfer through which the heat gets transferred in a vacuum.

Answer and Explanation:

Two shirts are warmer than a single shirt of double thickness because when somewhen wear two shirts a layer of air gets trapped between the two shirts and the air is a bad conductor of heat so this layer of air present between the two shirts behave like thermal insulation, hence trap the heat inside and keep the body warm. Where in case of a shirt with a double thickness no such possibility is there.
