Question

what is density? 150 words remaining

Explanation:

Density is a physical property. It is defined as mass per unit volume of a substance. Mathematically, density ($
ho$) = $\frac{m}{V}$, where $m$ is mass and $V$ is volume. Different substances have characteristic densities. For example, water has a density of approximately 1 g/cm³ at standard conditions. Density helps in identifying substances and understanding their physical - state behavior, like whether an object will float or sink in a liquid.

Answer:

Density is mass per unit volume of a substance, calculated as $
ho=\frac{m}{V}$, and is used to identify substances and understand physical - state behavior.
