Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Understanding the Concept of Boiling:** - Boiling occurs when a liquid reaches its boiling point, which is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure. For water, this is 100°C (212°F) at sea level. 2. **Material Properties:** - A paper cup is made of cellulose fibers, which can burn if they reach a high enough temperature (ignition temperature). The ignition temperature of paper is around 230°C (446°F). ...
