If you heat ice, it melts. This statement means that when you apply heat to ice, it changes from a solid state to a liquid state.
Explanation:
When ice is exposed to heat, the energy from the heat causes the ice molecules to vibrate faster. This increased molecular motion disrupts the crystal structure of the ice, breaking the bonds that hold the water molecules together. As a result, the ice melts and turns into liquid water.
Step-by-step solution:
To demonstrate this, you can perform a simple experiment. Here's what you'll need:
- A small piece of ice
- A heat source (e.g., a stove or a candle)
- A container to catch the melted water (e.g., a bowl or a cup)
1. Start by placing the piece of ice on a heat-safe surface.
2. Light the heat source and position it underneath the ice. Make sure to keep a safe distance to avoid any accidents.
3. Observe the ice as it comes into contact with the heat. Within a short period, you will see that the ice starts to melt and turns into liquid water.
4. During this process, you can explain to the student that the heat from the source is transferring energy to the ice, causing its molecules to gain kinetic energy and move faster.
5. As a result of the increased molecular motion, the ice molecules break apart and lose their rigid structure. This allows the ice to transform into water, which has a fluid and less ordered arrangement of molecules.
Conclusion:
By heating ice, we can observe the physical change of it melting and turning into liquid water. This experiment helps to explain the concept of heat transfer and the effects of energy on the state of matter.
