yes
Dissolving dissolving! Watch your grammar. The best example is sugar cube dissolving in a water. Best way to dissolve it is to smash it, put it in water and then stir it.
Sugar's dissolveable qualities.
temperature of water. :) and youre welcome(:
The dissolving of a sugar cube in water is a physical change, not a chemical change. This is because the sugar molecules are still present in the water; they have not undergone a chemical reaction to form new substances.
The process of a sugar cube dissolving in water is an example of physical weathering, specifically dissolution. The water breaks down the sugar cube into its individual molecules, resulting in its disappearance.
The air bubbles are trapped within the sugar cube and are released as the sugar dissolves in water. These air pockets are a result of the manufacturing process of the sugar cube, where they can get trapped during the compression of the sugar granules.
The sugar cube will dissolve in the warm water as it is soluble. Stirring will help to speed up the dissolving process by increasing the contact between the water and the sugar cube. Eventually, the sugar will completely dissolve in the water, resulting in a sweet solution.
This is a physical change the chemical composition of the sugar does not change
No, the dissolving of a sugar cube is a physical change, not a chemical change. The sugar molecules are still the same chemically; they are just dispersed in water instead of being in a solid form.
Yes, the "passive moving" of water across the membrane is considered osmosis.
Stirring increases the contact between the sugar cube and water, helping to dissolve the sugar faster. It helps break down the sugar cube into smaller particles, allowing more surface area to be exposed to the water. This speeds up the process of dissolving the sugar in water.
The sugar cube would dissolve faster when stirred. When you stir a sugar cube in water, you increase the rate at which molecules of sugar come into contact with water molecules, speeding up the dissolving process. Without stirring, the process is slower as diffusion is the only mechanism that helps the sugar dissolve.
