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.
Does filtration remove sugar from sugar water?
Filtration is not effective in removing sugar from sugar water because the sugar molecules are much smaller than the pores in the filter. To remove sugar from sugar water, processes like evaporation, crystallization, or distillation are more effective.
Why does sugar dissolve faster in hot tea than in cold water?
Hot fluid has a higher ability to dissolve solids like salt and sugar. This is how Rock Candy is made. You add as much sugar as possible to hot water, then when the water cools down, the sugar solidifies to everything it can. Hot water is just able to do this.
How could you prove that dissolving table salt in water is a physical change or not a chemical change?
well you know its not a chemical change when you see the salt dissolving because if your were to put something else like sugar then it would be a chemical change because the sugar would just float right to the bottom and stay there but salt would go around in the water and start dissolving.
Is adding salt to water a reversible change?
Yes, adding salt to water is a reversible change because the salt can be dissolved in the water to create a saltwater solution, which can then be separated back into salt and water through processes like evaporation or distillation.
Is sugar solution a compound or mixture?
It's a solution, since the sugar is dissolved in water.
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.
What is the difference between dissolving sugar in water and making cookies with sugar in them?
Dissolving sugar in water involves sugar molecules dispersing and mixing evenly throughout the water. Making cookies with sugar involves combining sugar with other ingredients like flour, eggs, and butter to create a dough that is then baked, resulting in a solid mixture with sugar crystals distributed throughout.
Why cant you heat sugar and water to separate it?
Heating sugar and water will not separate them because sugar dissolves in water to form a homogeneous solution. To separate them, you would need to use a physical method like evaporation to remove the water and obtain the sugar.
Does filtration remove sugar from sugar water?
Filtration is not effective in removing sugar from sugar water because the sugar molecules are much smaller than the pores in the filter. To remove sugar from sugar water, processes like evaporation, crystallization, or distillation are more effective.
Does sugar dissolve in ethyl acetate?
No, sugar does not dissolve in ethyl acetate because sugar is a polar molecule that is more likely to dissolve in polar solvents like water. Ethyl acetate is a nonpolar solvent and is not capable of dissolving polar substances like sugar.
What is the difference between dissolving and dissociation in the context of chemical reactions?
Dissolving refers to a physical process where a substance breaks down into smaller particles and mixes evenly with a solvent, like sugar dissolving in water. Dissociation, on the other hand, is a chemical process where compounds break apart into ions when dissolved in a solvent, like salt dissociating into sodium and chloride ions in water.
How can you change the melting point of ice?
By dissolving something in it, like salt or sugar.
Why does not sugar dissolve into Windex?
Sugar does not dissolve in Windex because Windex is a cleaning solution made up of water, ammonia, and alcohol. Sugar dissolves in water-based solutions but not in alcohol-based ones like Windex. The alcohol in Windex prevents sugar from dissolving because they have different solubility properties.
Why does sugar dissolve faster in hot tea than in cold water?
Hot fluid has a higher ability to dissolve solids like salt and sugar. This is how Rock Candy is made. You add as much sugar as possible to hot water, then when the water cools down, the sugar solidifies to everything it can. Hot water is just able to do this.

Which is true about sugar dissolving in water Sugar is the solvent and water is the solute. Both sugar and water are solvents. Sugar is the solute and water is the solvent. Both sugar and water are so?
One is going to be the solvent and one will be the solute, they can't be both at the same time. You usually put sugar into something such as water or tea or soda. That makes the sugar the solute (goes into) and the other, like water, the is the solvent. A good way to remember this is that the solvent is the part of a solution present in the largest amount.
