How does the process of freezing and melting affect the physical properties of a substance?
When a substance freezes, its molecules slow down and arrange into a solid structure, causing it to become more rigid and less fluid. This can lead to a decrease in volume and density. When the substance melts, the molecules gain energy and move more freely, returning to a liquid state. This can result in an increase in volume and density. Overall, the process of freezing and melting can alter the physical properties of a substance by changing its state from solid to liquid and vice versa.

What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties. The melting point is the temperature at which ice (solid) changes to water (liquid), while the freezing point is the temperature at which water (liquid) changes to ice (solid).
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.
How are melting and freezing points similar in a chemical?
Melting and freezing points are both physical properties of a substance related to its phase change from solid to liquid (melting) or liquid to solid (freezing) at a specific temperature. These points are the same temperature for a pure substance under constant pressure and can be used to identify and characterize substances.
Which of the following forms a new substance melting freezing evaporating burning?
Burning chemically alters a substance, creating different / new substances as a result. Melting, freezing, and evaporating are all different phases of the same substance.
What does the melting point graph reveal about the physical properties of the substance?
The melting point graph shows the temperature at which a substance changes from a solid to a liquid. It reveals the substance's melting point, which is a key physical property that can help identify and characterize the substance.
Are freezing and melting points characteristic properties?
Yes, freezing and melting points are characteristic properties of a substance. They are specific temperatures at which a substance changes its state from solid to liquid (melting) or from liquid to solid (freezing) under normal atmospheric pressure.
What are the two physical properties that can help you identify a substance?
Color, freezing point, or even texture if the substance is solid.
Is freezing a characteristic property?
Yes! Freezing (when a substance becomes solid) and melting points (when a substance becomes liquid) are characteristic properties.
Are melting and boiling point physical properties of a substance?
Yes, melting and boiling points are physical properties of a substance. They represent specific temperatures at which a substance transitions from one phase to another - solid to liquid for melting point, and liquid to gas for boiling point.
What kind of property is melting point and freezing point of water?
The melting point and freezing point of water are physical properties. The melting point is the temperature at which ice (solid) changes to water (liquid), while the freezing point is the temperature at which water (liquid) changes to ice (solid).

What Change that only affects the physical properties of substance is know as a?
A change that only affects the physical properties of a substance is known as a physical change. This type of change alters characteristics such as shape, size, and state of matter without affecting the chemical composition of the substance. Examples include melting, freezing, and dissolving. In a physical change, the substance remains the same at the molecular level.
Is freezing chemical or physical property?
I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property. Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.
Which of the following forms a new substance melting freezing evaporating burning?
Burning chemically alters a substance, creating different / new substances as a result. Melting, freezing, and evaporating are all different phases of the same substance.
What physical property identify a substance?
There are many varying physical properties used to identify a pure substance. Some of the most prevalent physical properties are color, odor, density, melting and freezing points and solubility.
Is conductivity intensive property?
Conductivity is an intensive property. Intensive properties are associated with the physical properties of a substance, and include things like melting point, ductility, malleability, density, and freezing point. These are characteristics of a substance that do not depend on the amount of the matter present.
