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.
Which type of property cannot be observed without changing the composition of a substance?
Chemical properties cannot be observed without changing its composition. ie: oxidation numbers Physical properties are properties such as melting point and boiling point. All that is needed to observe these are by placing the compound in a melting point apparatus etc.
What is the boiling point and freezing point of fahrenheit?
Fahrenheit is a person or a temperature scale, while boiling and freezing points are physical properties of chemicals. You need to be specific in asking which chemical's boiling and freezing points. Water has a freezing point of 32 degrees F, and a boiling point of 212 degrees F.
How does the phenomenon of freezing point depression and boiling point elevation affect the properties of a solution?
Freezing point depression and boiling point elevation are both colligative properties that occur when solute particles are added to a solvent. Freezing point depression lowers the temperature at which a solution freezes, while boiling point elevation raises the temperature at which a solution boils. These changes in the freezing and boiling points affect the physical properties of the solution, making it different from the pure solvent.
Is solute particles change the freezing and boiling points of solutions?
Yes, solute particles change the freezing and boiling points of solutions. This is known as colligative properties, where the presence of the solute affects the physical properties of the solvent. The freezing point decreases and the boiling point increases compared to the pure solvent.
Boiling points and freezing point are examples of?
Boiling point and freezing point are examples of physical properties of a substance, specifically referring to the temperature at which a substance transitions between different states of matter. Boiling point is the temperature at which a substance changes from a liquid to a gas, while freezing point is the temperature at which a substance changes from a liquid to a solid.
Is a boiling point a chemical property of a sustance?
No, boiling points and freezing points are physical properties.
What are boiling point and freezing point examples of?
Boiling point and freezing point are examples of physical properties of substances. Boiling point is the temperature at which a substance changes from a liquid to a gas, while freezing point is the temperature at which a substance changes from a liquid to a solid.
Is boiling points and freezing point are an example of a chemical property b physical property c energy or d matter?
Boiling point and freezing point are examples of physical properties. They describe the characteristics of a substance that can be observed or measured without changing the chemical composition of the substance.
Are boiling points and freezing points checimal changes?
No, boiling points and freezing points are not chemical changes. They are physical properties of a substance related to its phase transition between solid, liquid, and gas states. Chemical changes involve the formation of new substances with different chemical properties.
Does not change a substances identity physical or chemical change?
A physical change does not alter a substance's chemical composition; it only affects its physical properties like shape, size, or state of matter. Examples include melting, freezing, or boiling.
Is boiling point and freezing point matter?
Yes, boiling point and freezing point are physical properties that are specific to matter. The boiling point refers to the temperature at which a substance changes from a liquid to a gas, while the freezing point is the temperature at which a substance changes from a liquid to a solid. These properties vary depending on the chemical composition of the substance.
Why are physical processes like freezing and boiling not chemical reaction?
Freezing and boiling do not change the chemistry in the process.
Color odor boiling points melting points are all examples of what properties physical or chemical?
Physical
How can one show that element that have different appearances have similar chemical properties?
You can experiement with the melting point, boiling point, and freezing point of the elements to prove they have similar properties. This and you can check the different physical and other chemical properties for similarities and comparison.
What is freezing boiling and evaporation all examples of?
distillation
Are the changes in the state of matter chemical changes?
No, changes in state of matter (such as melting, freezing, boiling) are physical changes, not chemical changes. Chemical changes involve the formation of new substances with different chemical properties.
