Some properties, such as mass, depend on how much matter is present. Other properties, such as malleability, remain the same no matter how much matter is present. Which of these choices is a physical property of the element potassium that remains the same no matter how much matter is present? a. melting point b. volume c. flammability d. reactivity
The melting point. The volume obviously grows if the amount of matter can grow indefinitely. The reactivity is affected, with very small particles being highly reactive. Finally, the flammability is a type of reaction, so would fall under reactivity. Therefore, by process of elimination, its the melting point :D
