  • Topic: Heat transfer.

  • Why do we use a black umbrella in summer?

  • Hey.

  • Looks like you are heading out today.

  • But it is so hot outside.

  • Why don't you take a dark colored umbrella, preferably black?

  • See, I warned you.

  • At least now use the black umbrella.

  • Now, do you notice the heat?

  • No, right?

  • Do you know why?

  • This is because in summer season, the temperatures are quite high.

  • Now, as compared to other colors.

  • A black colored umbrella, being dark.

  • Absorbs most of the light and ultraviolet radiations coming from the sun and gets heated.

  • It then radiates the heat back into the air.

  • Thus, making a black umbrella, a good choice to use in summers.
