Which of these values is most responsible for changing the boiling and freezing points of a solvent?
The concentration of solute in the solvent is most responsible for changing the boiling and freezing points. When a solute is added to a solvent, it disrupts the normal intermolecular forces between solvent molecules, which results in a change in the boiling and freezing points of the solvent.
Melting freezing and boiling are what kind of change?
Melting, freezing, and boiling are physical changes, as they do not involve a change in the chemical composition of the substance.
Does salt make water hotter or colder?
No. Salt makes the freezing point of water lower and the boiling point higher. The particles of salt get in the way of crystal formation when freezing. They also get in the way of particles trying to escape when boiling.
What effects do solutes have on a solvent's freezing and boiling boints?
The effect of a solute on the freezing point and boiling point of a solvent is related to what is known as the colligative property. Upon addition of the solute, the freezing point will be lowered, and the boiling point will be increased. The magnitude of the change will depend on the solute and how many particles it forms upon dissolving, and on the nature of the solvent and the freezing/boiling point constant for that solvent.
What 2 things does antifreeze change?
because.... 333246 is the answer NOT!! :)
How does the vibration of particles change as the temperature moves between freezing and boiling?
The vibration of particles increase with the temperature.
What physical change of is the opposite of boiling?
the opposite of boiling is freezing

Why are physical processes like freezing and boiling not chemical reaction?
Freezing and boiling do not change the chemistry in the process.
Melting freezing and boiling are what kind of change?
Melting, freezing, and boiling are physical changes, as they do not involve a change in the chemical composition of the substance.
Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
Adding more solute to a solvent raises its boiling point and lowers its freezing point. This is known as boiling point elevation and freezing point depression. The presence of solute particles disrupts the organization of solvent molecules, making it more difficult for them to change phase.
Do colligative properties of solutions depend on the number of solute particles in a solution?
Yes, colligative properties, such as boiling point elevation and freezing point depression, depend on the number of solute particles present in a solution rather than the type of solute. More solute particles lead to a greater change in the colligative properties of the solution.
Does salt make water hotter or colder?
No. Salt makes the freezing point of water lower and the boiling point higher. The particles of salt get in the way of crystal formation when freezing. They also get in the way of particles trying to escape when boiling.
How does water change its state?
By freezing, melting or boiling.
What is of a physical change?
Freezing or boiling are physical changes.
At what temperature does water change from freezing to boiling?
Water changes from freezing to boiling at 100 degrees Celsius (212 degrees Fahrenheit).
What is an example of a change in state?
Boiling (or freezing) water (the change to steam or ice).
