Study Notes
Physical Properties of Matter
- Intensive physical properties include boiling point, density, state of matter, color, melting point, odor, temperature, refractive index, luster, hardness, ductility, malleability, electrical conductivity, and solubility.
- Extensive physical properties include volume, mass, size, weight, and length.
- Chemical properties entail the potential for a substance to undergo a chemical change or reaction through its composition.
- Density, expressed as mass per unit volume, is an intensive property and is generally in grams per cubic centimeter or kilograms per cubic meter.
- Density is not affected by the quantity of matter, making it an intensive property, and can differ based on the state of matter.
- Odor is an intensive physical property of matter, as it is observable and does not change the identity of a substance.
- Color is a physical property that can be determined without altering the substance's composition and is another example of an intensive property.
- Hardness, defined as the ability to resist fracture or deformation, is an intensive physical property.
- Length is an extensive physical property, referring to the longest dimension of an object, and can be measured in various units.
- Melting point, the temperature at which a solid melts, is an intensive property and varies based on the substance.
- Volume, the amount of 3D space enclosed by a closed surface, is an extensive property and can be measured in cubic or metric units.
- A phase change, or state change, refers to the transition between solid, liquid, and gas states, with melting being the process of a solid becoming a liquid.
