physical property
Học thuậtThân thiện
A scientist measures the physical property of density using a graduated cylinder and a balance.
Definition
Noun: A physical property is any measurable or observable characteristic of a material or system that describes its physical state and interactions without changing the substance's chemical identity. These properties can be used to characterize matter and energy.
Usage
A physical property describes an attribute of a substance that can be determined without altering its fundamental composition. It is a key concept in physics and chemistry for identifying and classifying materials.
Examples
- Density is a fundamental physical property of matter.
- Scientists measured the physical properties of the new alloy, including its electrical conductivity and melting point.
- Color, hardness, and boiling point are all examples of physical properties.
Advanced Usage
- Intensive vs. Extensive Properties: Physical properties are often categorized as intensive (independent of the amount of matter, like density or temperature) or extensive (dependent on the amount, like mass or volume).
- In materials science, the analysis of physical properties is crucial for engineering applications.
Variants and Related Words
- Physical: (Adjective) Of or relating to physics or the properties of matter and energy.
- The physical state of water changes from liquid to solid at 0°C.
- Property: (Noun) A quality or trait belonging to a person or thing.
- One characteristic property of gold is its malleability.
Synonyms
- Attribute
- Characteristic
- Trait
- Parameter (in a scientific context)
Antonyms
- Chemical property: A property that describes a substance's ability to undergo a specific chemical change.
