Question

Which are physical properties? (Select all that apply.)

volume

melting point

appearance

formation of bubbles

Answer 1

Physical properties include:

- **Volume**: This is a measure of the amount of space that a substance occupies.
- **Melting Point**: This is the temperature at which a solid turns into a liquid.
- **Appearance**: This refers to the visual characteristics of a substance, such as color, texture, and state (solid, liquid, gas).

**Formation of bubbles**, however, is not a physical property; it often indicates a chemical reaction or a change in state (such as boiling).

So the physical properties from your list are: **volume, melting point, and appearance.**
