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.

Yes, coconut oil often solidifies in winter due to the lower temperatures. When the temperature drops below 24°C, it reaches its freezing point and changes from liquid to solid, demonstrating the transformation between different states of matter.
Other liquids that convert into solids include chocolate and gelatin. Chocolate hardens when cooled after melting, and gelatin transforms into a solid gel as it cools and sets. Both processes involve cooling the liquid to below its freezing point.
To change liquid wax back to a solid state, allow it to cool and solidify. As the temperature drops below the wax’s freezing point, it will transition from liquid to solid. This can be sped up by placing it in ...
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.
An example of a substance changing from solid to liquid is ice cream. When ice cream is taken out of the freezer and warms up, it melts from a solid to a liquid state.
On a hot day, evaporation occurs faster due to higher temperatures providing more energy for water molecules to escape into the air. On a cold day, evaporation is slower because there is less thermal energy available.
Water evaporation speed is influenced by temperature, humidity, air movement, and surface area. Higher temperatures and lower humidity increase evaporation, while more air movement speeds it up. Larger surface areas also facilitate faster evaporation.
Clothes dry faster on a windy day because the wind increases air circulation, which speeds up evaporation. The moving air helps remove moisture from the surface of the clothes more efficiently than still air.
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.
