Option C. is correct because Density =Mass/Volume
if other materials have same volume with that of metals than metals have much weight than other materials or they have more mass per unit volume.In the sense they are heavier than other materials
14. The metals are denser than other materials. This means that a. That can be worked...
2. Iron is denser than plastic. When fully submerged in water, is the buoyant force on a solid iron sphere greater than, less than, or equal to the buoyant force on a solid plastic sphere of the same diameter? Explain your answer using the buoyant force equation. a. b. If you instead fully submerge each sphere in ethylene glycol, does the buoyant force on each sphere increase, decrease, or stay the same. Explain your answer using the buoyant force equation....
Some metals form crusty oxide layers that can flake off to expose clean metal surfaces to moisture and air. Other metals form oxide layers that are durable and relatively impermeable. Use this fact to explain why aluminum, a more active metal than iron, is less susceptible to corrosion.
