Question: Can we boil water in a paper cup explain?

The paper will ignite around 230 degrees Celsius and water boils at 100 degrees Celsius. Although the fire is hot enough to ignite the paper cup, the heat energy is absorbed by the water, causing it to boil.

Can you boil water in a paper cup explain?

Water can be boiled in a paper cup because, the heat energy supplied to paper cup rapidly passes on to water. Thus, ignition temperature of paper is not achieved and, hence, it does not catch fire.

What will happen when a paper cup with water is heated?

When paper cup is heated containing water, water absorbs the heat coming from the burning source and thus prevents the paper from reaching its ignition point. Hence it does not burn. Water in the cup becomes hot instead.

How can water be boiled in a thin paper cup?

The paper cup in which water is placed is having ignition temperature higher than the boiling point of water, and water have high latent heat of vaporization. This is also possible that temperature provided to water does not exceed its boiling point. Hence, water can boil in paper cup without burning the cup.

Can you put boiling water in plastic cup?

No, it is not. Hot liquid causes a potentially harmful chemical to leach out of certain plastics much faster than usual, researchers have found. … The chemicals contained in plastics can be quite harmful.

Can hot water melt Styrofoam?

Styrofoam is an insulator, making it very poor at conducting heat. Heat can’t pass on through to the water, so the Styrofoam disintegrates. Now go ahead and bet a friend or family member that you can boil water in a Styrofoam cup. Then do it!

How long will paper cups hold water?

The quality is high enough that the recycled pulp can be turned into copy-grade paper, as the paperboard contains a large amount of short fibres. When tested, cups lined with the new coating were found to be able to hold hot and soft drinks for more than 2 days.

Why does paper cup filled with water not catch fire?

Complete answer:

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.
