The Vietnamese word "hoạt tính" can be translated to "active" in English. It is often used in various contexts, particularly in chemistry and environmental science.

Basic Explanation:

"Hoạt tính" refers to the ability of a substance to react or interact actively with other substances. A common example is "than hoạt tính," which means "activated carbon." This type of carbon has been processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions.

Usage Instructions:

1. In Chemistry: You can use "hoạt tính" to describe substances that have a high reactivity or effectiveness in chemical reactions.
2. In Everyday Language: It can describe someone or something that is energetic or dynamic.

Example:

• In Science: "Than hoạt tính được sử dụng để lọc nước." (Activated carbon is used to filter water.)
• In Daily Life: "Cô ấy rất hoạt tính, luôn tham gia vào các hoạt động xã hội." (She is very active, always participating in social activities.)

Advanced Usage:

In more advanced contexts, "hoạt tính" can also refer to the reactivity or effectiveness of a catalyst in chemical reactions. For example, you might say, "Hoạt tính của chất xúc tác này rất cao." (The activity of this catalyst is very high.)

Word Variants:

• "Hoạt động": This means "activity" or "operation."
• "Hoạt bát": This means "lively" or "energetic," often used to describe a person's character.

Different Meanings:

While "hoạt tính" primarily means "active" in a chemical or energetic sense, it can also imply effectiveness or efficiency in a broader context, such as processes or actions.
