Answer: When clothes are spread out, the surface area exposed to infrared radiation increases. This will allow clothes to receive more infrared radiation. The amount of infrared radiation absorbed or emitted depends on the amount of surface area exposed to infrared radiation.
Tip: The rate at which infrared radiation is emitted or absorbed depends on the surface area, temperature of the body, the colour of the body and the texture of the body.
