Boiling, Chopping Crushing, Cutting, Freezing, Grinding, Melting Molding, Pounding, Smashing.
Mixing sand and sugar is it reversible or irreversible?
Irreversible
Sugar dissolving in water is an example of what process?
The formation of a solution, in which sugar is the solute, and water is the solvent.
What is the particle theory of dissolving?
When a solid dissolves, the solid (solute) and the liquid (solvent) will form solution. When a solid dissolves on mixing, its particles will break apart hence forming loose associations with the liquid particles. This random mixing of particles from both solid and liquid that is called dissolving process. A solid will not dissolve in a liquid if its particles are unable to form these association with the respective liquid particles. This is a reversible process. Solute can be obtained back by evaporation etc.
Is mixing salt and sugar a physial change?
No, mixing sugar and chocolate is not a chemical change. It's a physical change.
Dissolving sugar in water is an example of a physical change.?
Reversible
Is dissolving sugar in a cup of tea reversible?
no
When sugar is dissolving is that a chemical or physical change?
The change is physical because the change is reversible. Evaporate the water and you are left with the sugar, no new substances are produced; the sugar stays sugar and the water, water.
Is sugar dissolving an example of chemical change?
It is a physical change.
Can sugar dissolving water be reversible?
Yes, the process of sugar dissolving in water is reversible. Sugar molecules disperse in water but do not undergo any chemical change. By evaporation, the water can be removed, leaving behind solid sugar crystals.
Dissolving a spoonful of sugar in tea or coffee is an example of an?
a physical change
Is dissolving sugar physical or chemical?
Sugar dissolving would be an example of a physical change. This is because it does not change chemically, so it is still sugar.
Is dissolving sugar in hot tea an example of a chemical change?
No, dissolving sugar in hot tea is a physical change, not a chemical change. The sugar molecules are still present in the tea and can be separated by processes like evaporation. The chemical composition of the sugar does not change during the dissolving process.
Why is dissolving sugar in water a reversible change?
It’s reversible
True or false the dissolving of sugar in water is an example of a chemial change?
false - it's a physical change. The sugar remains sugar only in solution.
How do you know that dissolving surgar in water is a physical change and not a chemical change?
Dissolving sugar in water is a physical change because the chemical composition of sugar (C12H22O11) remains the same before and after dissolving. No new substances are formed. It is a reversible process where the molecules of sugar disperse throughout the water, but they can be brought back together by evaporating the water.
