A physical change can happen without changing any of the characteristics, for example if you have an ice cube which is frozen H2O and you let it sit it will melt only changing the physical appearance and the molecules in the substance. A physical change doesn't change the physical composition.

D No cap tell me if dis helped <3
If a liquid does not have a constant boiling point but it looks the same throughout, then the liquid is probably a homogeneous mixture. A liquid that does not have a constant boiling point would mean that it is not a pure liquid, it would be a mixture of different substances. As stated, the liquid is observed to be the same all throughout then it most likely is homogeneous. Homogeneous mixture are mixture which has the same composition of the components at any point of the mixture. So, it would have uniform properties as well. Examples of this type of mixture would be soda, coffee, tea and juices.<span />

Answer:
C) The mass will double.
Explanation:
The amount of solute that will dissolve will also double since the solvent volume has doubled.
There is a fine liner relationship between amount of solute and solvent that can form a solution.
- A solute is the substance that is dissolved in another.
- A solvent is the medium by which a solute is dissolved.
- A combination of solute and solvent forms a mixture called solution.
To form a solution, solvation must take place. During solvation, the molecules of the solvent surrounds the solute completely and bring them into the phase of dissolution.
Generally, the more the solvent, the more the solute it is able to dissolve.
A table spoon of sugar for example will dissolve readily in a jar of water without settling. In a bucket, it is even much more easier.
