When a fluid cools, its molecules lose energy and move more slowly, causing the fluid to contract and become denser. Eventually, the fluid may reach its freezing point and solidify into a solid state.
This process describes the convection current, where warm fluid rises due to its lower density and cooler fluid sinks due to its higher density. This continuous circulation helps transfer heat within a fluid, such as in the Earth's mantle or in a pot of boiling water.
When water vapor cools down, it undergoes condensation and turns back into liquid water. This process releases heat energy into the surrounding environment.
When something cools, its temperature decreases, causing the molecules in the material to slow down and move closer together. This can lead to changes in physical properties, such as solidification or contraction.
This phenomenon is known as convection. When a fluid is heated, it becomes less dense and rises, creating a flow that redistributes the heat. Conversely, as the fluid cools, it becomes denser and sinks, completing the convection cycle.
As the beaker cools down, the thermal energy within it decreases. This results in a transfer of heat from the beaker to its surroundings, causing the temperature of the beaker to drop.
Use particle theory of matter to describe what happens to the density of a substance when it cools down
