Cách sử dụng
Porosity is a word that describes the amount of empty space or holes in something. We can use it to talk about materials like rocks, soil, or even our skin. If something has high porosity, it means there are a lot of empty spaces or gaps inside it. If something has low porosity, it means there aren't many empty spaces or gaps. Scientists might talk about porosity when they're studying how different materials react to water or air. For example, soil with high porosity might absorb more water than soil with low porosity. Overall, porosity is a useful word when talking about how much space is available in something.
