Physical and Chemical Properties and Changes

What is the definition of physical property?

• Characteristic of a substance that can be observed without changing it.
• Any quality that can be established only by changing a substance's chemical identity.

Definition of melting point:

• Temperature that a substance reaches when it turns from a solid to a liquid.
• Temperature that a substance reaches when it turns from a liquid to a gas.

Definition of boiling point:

• Temperature that a substance reaches when it turns from a solid to a liquid.
• Temperature that a substance reaches when it turns from a liquid to a gas.

Definition of viscosity:

• The state of being thick & sticky due to internal friction.
• The consistency feel or appearance of a substance.

Definition of solubility:

• The quality or state of shining by reflecting light.
• A measure of how much a substance dissolves in a given volume of liquid.

Definition of hardness:

• Condition or quality of being hard.
• A property of matter showing the mass per unit volume.

Definition of state/phase of matter:

• The properties of attraction possessed by magnets.
• The different forms that matter exists in most commonly known as solids, liquids and gases.
