What dissolves sugar but not crystal meth?
Water is effective at dissolving sugar due to its polar nature, but crystal meth is not very soluble in water. However, substances such as acetone or other organic solvents are more efficient at dissolving crystal meth while not dissolving sugar.
What is the dissolving rate of a bouillon cube?
The dissolving rate of a bouillon cube can vary depending on factors such as temperature of the water, size of the cube, and how agitated the water is. In general, a bouillon cube should fully dissolve within 1-2 minutes in hot water.
Do melting and dissolving have the same meaning?
Melting and dissolving are not the same. Melting is the process of a solid turning into a liquid due to heat, while dissolving is when a solid substance mixes with a liquid to form a solution.
Why does water not dissolve motor oil?
Water and motor oil are immiscible because they have different polarities. Water is a polar molecule, while motor oil is nonpolar. This difference in polarity prevents water from dissolving motor oil.
What is a soluble substance?
A soluble substance is a substance that can dissolve in a particular solvent to form a homogeneous mixture. This means that the soluble substance breaks down into particles small enough to be evenly dispersed throughout the solvent. Examples include sugar dissolving in water or salt dissolving in vinegar.
What is the independent and dependent variables when you water plants with milk or water?
The independent variables are the milk and water, while the dependent variables are the plants, because they don't change.
Does dissolving always involve water?
No, dissolving does not always involve water. Dissolving is a process where a solute mixes with a solvent to form a homogeneous mixture. While water is a common solvent that is often used for dissolving substances, other solvents such as alcohol or acetone can also be used depending on the substances being dissolved.
Is dissolving a LIFESAVER candy in warm water melting?
No, dissolving a LIFESAVER candy in warm water is not considered melting. Melting typically refers to a solid turning into a liquid due to heat, while dissolving involves a solid substance breaking down into individual molecules and dispersing throughout a solvent, in this case, water.
What dissolves sugar but not crystal meth?
Water is effective at dissolving sugar due to its polar nature, but crystal meth is not very soluble in water. However, substances such as acetone or other organic solvents are more efficient at dissolving crystal meth while not dissolving sugar.

Why is salt in water a physical change?
Dissolving salt into water is a physical change because no chemical reaction takes place, while the state of matter of the salt changes.
What variables are maintained while the browser is opened?
Session Variables
What are the variables of does sugar dissolving faster in hot or cold water?
Temperature: more sugar will dissolve in water at a higher temperature. The amount of water is also a factor, since more water will be able to dissolve more sugar. If you are wondering about the rate, and not simply the amount, of sugar dissolving, then the surface area of the particles is also important. The greater the surface area, the more rapidly it will dissolve (smaller grains of sugar would dissolve more rapidly than a sugar cube, for instance).
Do melting and dissolving have the same meaning?
Melting and dissolving are not the same. Melting is the process of a solid turning into a liquid due to heat, while dissolving is when a solid substance mixes with a liquid to form a solution.
What is the solute and the solvent of the vinegar?
Vinegar is basically a solution of acetic acid in water. Therefore acetic acid is the solute and water is the solvent. See this site for information about dissolving and solutions: http://www.bbc.co.uk/schools/ks3bitesize/science/chemistry/physical_changes_8.shtml
Why is butane not soluble in water?
Butane is a nonpolar molecule, while water is a polar molecule. Nonpolar molecules like butane are not attracted to the polar water molecules, making it insoluble in water. This lack of interaction between the molecules prevents butane from dissolving in water.
How can table salt be separated from a mixture of table salt and talcum powder?
One way to separate table salt from talcum powder is by dissolving the mixture in water. Salt will dissolve in water while talcum powder will not. After dissolving, the saltwater solution can be filtered to separate the salt from the talcum powder. The water can then be evaporated to recover the salt.
