standard temperature

Thân thiện

The scientist records the standard temperature of the melting ice.

Definition

1. Noun:
   • A precisely defined reference point on the temperature scale: "standard temperature" specifically refers to the exact value of zero degrees Celsius (0°C). This fixed point is used in scientific contexts, particularly in physics and chemistry, as a fundamental reference for measurements and calculations, such as in gas laws (e.g., Standard Temperature and Pressure, STP).

Usage

• "Standard temperature" is primarily used as a scientific and technical term. It denotes a constant, agreed-upon value that serves as a baseline for comparison, ensuring consistency in experiments and industrial processes.
• It is most commonly encountered in the combined phrase "Standard Temperature and Pressure" (STP).

Examples

• Noun:
  • The volume of the gas was calculated at standard temperature.
  • In many equations, properties are defined relative to standard temperature.

Advanced Usage

• "Standard Temperature and Pressure (STP)": A standard condition defined as a temperature of 0°C (273.15 K) and a pressure of 1 atmosphere (101.325 kPa), used for reporting measurements of gases.
  • The molar volume of an ideal gas at STP is 22.4 liters.

Variants and Related Words

• STP (abbreviation): Stands for Standard Temperature and Pressure.
• Standard conditions: A broader term that may include standard temperature along with other defined parameters like pressure and concentration.
• Normal temperature: In some historical or specific technical contexts, this can be synonymous, but "standard temperature" is the more precise, universally accepted term in modern science.

Synonyms

• Zero degrees Celsius
• 273.15 Kelvin (the equivalent temperature on the Kelvin scale).

Related Phrases

• At standard temperature: Under conditions where the temperature is precisely 0°C.
  • The experiment must be conducted at standard temperature for valid results.
