* Density is Key: Mass and volume are related through density. Density is the amount of mass per unit volume. The formula is:
* Density (ρ) = Mass (m) / Volume (V)
* Scenario 1: Constant Density: If the density remains constant, then tripling the volume will also triple the mass. This would be the case for a substance that is not compressed or expanded.
* Scenario 2: Changing Density: If the density changes, then the relationship between mass and volume becomes more complex. For example:
* Compression: If you compress a gas, you're increasing its density. Tripling the volume might actually decrease the mass if the gas is escaping during compression.
* Expansion: If you heat a substance, it might expand. Tripling the volume could lead to a smaller increase in mass, or even a decrease if some of the substance evaporates.
In summary: To know how mass changes when volume is tripled, you need to know how the density changes.
