    False. The density of a specific substance can change under various conditions, such as changes in temperature or pressure. For example, heating a substance generally decreases its density because it expands, while increasing pressure can increase the density by compressing the substance.

    Yes, I'm sure. The density of a substance is defined as its mass per unit volume (density = mass/volume). While the intrinsic properties of a substance remain constant, external factors like temperature and pressure can affect how closely the molecules are packed together, thus changing the volume. 
- **Temperature**: When a substance is heated, its particles typically move apart, increasing its volume and decreasing its density. Conversely, when cooled, its particles come closer together, decreasing its volume and increasing its density.
- **Pressure**: Increased pressure typically compresses substances, especially gases, thereby decreasing their volume and increasing their density.
So, while a substance has a specific density at a standard temperature and pressure (often given in reference tables), that density can change under varying conditions.

    Yes, it is false to say that the density of a specific substance never changes. Density can change with variations in temperature and pressure, among other factors.
