Question
Can you boil water in a paper cup? Explain.
✓

Answer

Yes, we can boil water in the paper cup due to the following reason.

  • Most type of paper bums at about 230°C.
  • Water can pass at the bottom through pores of the paper.
  • Hot water rises up due to hot conventional current and replaces the cold water.
  • Water boils at 100°C.

The heat of bums warms the water which rises up in a cup, by replacing cold water so heat does not heat up the paper. So water boils in a cup of paper.
