How hot can a paper cup get?

A paper cup can get as hot as the liquid inside it, reaching 100°C (212°F), the boiling point of water, because the water absorbs the heat and prevents the paper from combusting, though the outside may char or get soft. Standard hot cups are lined with plastic (polyethylene) to handle temperatures around 90-100°C (194-212°F), but without liquid, paper burns at a much higher temperature (around 223°C).

Can water be boiled in a paper cup without burning it?

A flame is put beneath the cup and eventually the water boils without burning the cup.

So the choice is up to you really. Plastic cups are cheaper but are only good for cold drinks. Paper cups are somewhat less eco-friendly but prevent thermal burns. We recommend a combination of the two for maximum effectiveness.

Why does paper cup with water not burn?

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. This is because of the absorption of heat by water in it.
