Real-world examples of solids turning into liquids for kids

📚 Quick Study Guide

• 🧊 Melting: This is when a solid turns into a liquid because it gets warmer. Think of an ice cube!
• 🌡️ Temperature: Different solids melt at different temperatures. For example, ice melts at 0°C (32°F).
• 🍫 Examples: Many things melt, like chocolate, butter, and even some metals when they get hot enough!
• 🧪 States of Matter: Solids, liquids, and gases are the three common states of matter. Melting is a change of state.
• 💡 Fun Fact: Some solids, like dry ice, don't melt into a liquid. They turn directly into a gas in a process called sublimation!
