Why we can easily boil water in a paper cup?

Paper ignites at a much higher temperature than the boiling point of water. … Although the fire is hot enough to ignite the paper cup, the heat energy is absorbed by the water, causing it to boil. The water acts as a heat sink using the heat from the flame to heat up and boil.

What happens when water is heated in a paper cup?

If the paper cup is heated carrying water, the water will be absorbing the heat coming from the burning source and thus stops the paper from reaching its ignition point. Therefore it will not burn. Instead of this, water in the cup becomes hot.

Can we boil water in a paper cup while paper catches fire easily?

we can boil water in a paper while empty paper catches fire easily because the heat is continuously absorbed by the water which prevents the paper cup from burning…

Can you put hot water in paper cups?

What happens to the paper cup?

The empty paper cup catches fire easily and starts burning because the ignition temperature of paper reaches quickly. … So, in the presence of water, the ignition temperature of paper cup is not reached, and hence the paper cup does not catch fire.

Which can transfer more heat a cup of boiling water or a cup of tap water?

This means if two objects are at the same temperature but one has more mass than the other, the object with more mass has more thermal energy. So while both the cup and pot of water have the same temperature, the pot has more thermal energy due to having more molecules that vibrate than the cup of water.

Can you boil water in microwave in paper cup?

Paper hot cups and soup cups are designed to hold hot drinks and food, but not to withstand the extreme heat of a microwave. At best, the glue at the seam can loosen and the cup will start to leak. At worst, the cups can even catch on fire!
