The Vietnamese word "nội năng" translates to "internal energy" in English. It refers to the energy contained within a system or substance, which can include both kinetic and potential energy at the microscopic level.

Usage Instructions:

• "Nội năng" is commonly used in scientific contexts, particularly in physics and thermodynamics.
• You can use it when discussing topics related to energy, heat transfer, and the properties of materials.

Example Sentence:

• "Nội năng của một vật thể có thể thay đổi khi nhiệt độ của nó thay đổi." (The internal energy of an object can change when its temperature changes.)

Advanced Usage:

In advanced discussions, you might encounter "nội năng" in relation to the laws of thermodynamics, where it's important to understand how energy is transferred or transformed within systems. For example, you could discuss how the internal energy of a gas changes when it expands or is compressed.

Word Variants:

• "Năng lượng" (energy) can be used in broader contexts, while "nội năng" is specifically about internal energy.
• Related terms include "nhiệt năng" (thermal energy) and "động năng" (kinetic energy), which are components of internal energy.

Different Meanings:

While "nội năng" primarily refers to internal energy in a scientific sense, in a metaphorical context, it could be used to describe someone's inner strength or vitality.

Synonyms:

• "Năng lượng bên trong" (internal energy) is another way to express the concept.
• "Năng lượng nội tại" (intrinsic energy) can also be used, though it's less common.

Conclusion:

Understanding "nội năng" is essential for discussions in physics or engineering, especially when exploring how energy behaves in different states and processes.
