When a sugar cube is dropped in cold water, the sugar molecules start to dissolve due to diffusion. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration to achieve equilibrium. As the sugar molecules spread out in the water, the sugar cube eventually dissolves completely.

Is a sugar cube dropped in hot water an example of diffusion?

Yes, a sugar cube dropped in hot water is an example of diffusion. The sugar molecules move from an area of higher concentration (the sugar cube) to an area of lower concentration (the hot water) until they are evenly distributed. This process is a type of diffusion called passive diffusion.


Sentence with osmosis and diffusion to describe what happens when a tea bag and a spoonful of sugar are placed in a cup of hot water?

When a tea bag and a spoonful of sugar are placed in hot water, diffusion allows the sugar molecules to move from an area of high concentration to a lower concentration throughout the water, sweetening it. Osmosis causes water to move into the tea bag, allowing the flavor compounds to diffuse out and infuse the water.


Do cells have to work to make osmosis happen?

No, osmosis is a type of diffusion. Diffusion never requires work. Osmosis occurs when water seeks equilibrium. The water will naturally try to have the same amount of solvents in it without work from the cell. You can do osmosis experiments using a dialysis bag. Put solvent (such as sugar) in the bag with some water. Then put the bag in a cup of water. Watch what happens :)


Diffusion of water molecules?

Happens a lot.


Sugar cube in hot water is simple diffusion?

Yes, when a sugar cube dissolves in hot water, it is a form of simple diffusion. The sugar molecules move from an area of higher concentration (sugar cube) to an area of lower concentration (water) until equilibrium is reached.


What is the name of the molecule movement when sugar has dissolved into water?

diffusion


What happens sugar is added to water?

The sugar will dissolve in water because sugar is polar and so is water with hydrogen bonds. When attraction happens, the water molecules will separate the sugar molecules and the sugar will be dissolved.


Use diffusion to explain what happens what happens when you drop a sugar cube in a cup?

When a cube of sugar is dropped in a cup of solvent like water or milk the molecules of sugar start diffusing from its block to the solvent by their own kinetic energy so as to make a uniform solution of the solute (sugar) and the solvent (water or milk).


What is the process called when a sugar cube melts in a cup water?

The process is called dissolution. It involves the sugar particles becoming dispersed in the water, forming a sugar-water solution.


What happens when water and sugar are mixed?

The sugar disinigrates and is part of the water


What happens when you mix water and sugar?

The sugar will dissolve in the water, changing the sugar from solid to liquid.


What happens if sugar mixed with water is frozen?

its like a sugar cube. you have sugar and water then it freezes. then the water is sweet. so therefore its a sugar cube
