In the solid state, water (ice) is rigid with fixed shape. As a liquid, water flows freely and takes the container’s shape. In the gaseous state (steam), water molecules move rapidly and spread out in all directions.

Yes, the smell of food spreads without entering the kitchen because of diffusion. The aroma, carried by air particles, travels from the kitchen to surrounding areas, allowing us to detect it without being close.
To quickly change ice to water, increase its temperature above 0°C. This can be done by applying heat, placing the ice in a warm environment, or using hot water, causing the ice to melt faster.
Atmospheric Water Generator (AWG) machines extract moisture from the air and convert it into drinking water. They use cooling or desiccation methods to condense water vapor, making them a reliable source in areas with water scarcity.
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.
