Why does the volume of sugar solution remain same but the weight increases?
The volume of the resulting solution is actually increased. As a rule of thumb the extra volume is about 60% of the kg mass taken in litres.Example: 1 L water + 1 kg sugar will take 1 L + 0.60L = 1.6 L(with total mass of 2 kg solution)
When sugar is dissolved in water What about its weight?
The mass of both solute and solvent are conserved (sugar water weighs the same as the sugar plus the water), the volume of the solution increases less than the dry volume of the sugar, so the density of the solution is higher than water.
Is the preparation of sugar solution physical change?
Yes. Both the sugar and the water (or other solvent) remain the same chemicals. Since no chemical change occurs during creation of the solution, it is a physical change.
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.
Infer What can you infer about the size of sugar particles that are dissolves in a mixture of sugar and water?
I have a little leaky dingy, would you like to ride it? It has a mind of its own.

When sugar dissolve in water there is no change in volume?
Yes there is a change in volume.
What colour of sugar solution on litmus paper?
Litmus does not change color in sugar solution.
Does conductivitiy of water change as concentration of sugar change?
No. Sugar solution is not an electrolyte because it has no free charges in the solution to carry the electricity.
Formula for finding distance?
if the concentration of sugar solution of volume of 360 cm3 cube is 0.785 mol/ dm3 has the mass of 25g of sugar present in the solution. work out for the mole of the sugar content in the solution.

Is it a physical change when a sugar and water solution is evaporated?
no
How many grams sugar need to be added in a 100mL water to make a 10 sugar solution?
To make a 10% sugar solution you need to dissolve 10 grams of sugar and bring the volume up to 100 ml
Why will be change in the potato cube in concentrated sugar solution and distilled water respectively after an hour?
In sugar solution the potato cube absorb the solution , but in distilled solution the cube do not absorb it.
How can you determine if a substance is a salt or a sugar?
Test for sugar with Benidict's solution... if it doesn't change color, It is not sugar if it does it is!!!! :)
