đoạn nhiệt

Friendly

The Vietnamese term "đoạn nhiệt" refers to the concept of "adiabatic" in physics. In simple terms, it describes a process in which no heat is transferred into or out of a system. This means that all the energy changes in the system are due to work done on or by the system, rather than heat exchange.

Usage Instructions:

• "Đoạn nhiệt" is primarily used in physics, particularly in thermodynamics.
• It is often used when discussing processes involving gases, such as expansion or compression, where heat does not enter or leave the system.

Example:

• In an adiabatic process, when a gas expands, it does work on its surroundings and cools down without absorbing heat from the environment. This can be described in Vietnamese as: "Trong một đoạn nhiệt, khi khí nở ra, nó thực hiện công lên môi trường xung quanh và làm lạnh mà không hấp thụ nhiệt từ môi trường."

Advanced Usage:

• In advanced physics, "đoạn nhiệt" may be discussed in the context of the first law of thermodynamics, where it emphasizes the conservation of energy in adiabatic processes.
• For example, during adiabatic compression of a gas in a piston, the internal energy increases due to work done on the gas, resulting in a rise in temperature.

Word Variants:

• There are no direct variants of "đoạn nhiệt," but related terms include:
  • "hệ thống đoạn nhiệt" (adiabatic system)
  • "quá trình đoạn nhiệt" (adiabatic process)

Different Meanings:

• While "đoạn nhiệt" primarily refers to the adiabatic process in physics, it does not have widely recognized alternative meanings in everyday language.

Synonyms:

• In the context of thermodynamics, "đoạn nhiệt" can be synonymous with "quá trình không có truyền nhiệt" (heat-exchange-free process).
