To change water into ice, lower the temperature to 0°C or below. When water is cooled to its freezing point, it undergoes a phase change from liquid to solid, turning into ice due to decreased molecular movement.

To turn candle wax into a liquid state, heat it gently. The heat raises the wax’s temperature, causing it to melt. Use a heat source like a candle warmer or a pot of hot water.
To speed up drying clothes on a rainy day, use a fan or dehumidifier to increase air circulation and reduce humidity. Alternatively, use a heater to warm the air, which enhances evaporation.
We can change the states of water by altering its temperature. Cooling water turns it into ice (solid), while heating it changes it into steam (gas). These processes involve freezing, melting, boiling, and condensation.
When water is sprinkled on a hot pan, it evaporates quickly. The heat causes the water to change from liquid to vapor, which disperses into the air, making it seem like it has disappeared.
