Real-world examples of evaporation in your home and nature.

📚 Quick Study Guide

• 💧 Evaporation is the process where a liquid changes into a gas.
• ☀️ Heat increases the rate of evaporation. Higher temperature means faster evaporation.
• 💨 Airflow also increases evaporation. Wind helps carry away vapor.
• 👕 Surface area matters! Larger surface area = faster evaporation.
• 🌡️ Humidity decreases evaporation. High humidity means the air is already saturated with water vapor.
• 🧊 Sublimation is similar to evaporation, but it involves a solid changing directly into a gas. Think dry ice!
