To determine which layer of liquid or object has the least amount of density, it’s important to consider the general densities of the options provided:
- Bolt - Typically made of metal, it has a high density.
- Vegetable Oil - Generally has a low density compared to water but is denser than many objects.
- Ping Pong Ball - Made of lightweight plastic, it is very low in density.
- Popcorn Kernel - A dry kernel is relatively light, but when popped, it becomes very airy and has a low density.
Among these options, the ping pong ball would likely have the least density when compared to a bolt and vegetable oil, while in its popped state, popcorn could have a lower density than the ping pong ball. However, typically, a popped popcorn kernel would be the lightest option due to its airy structure.
Final Answer: Popped popcorn kernel (if context indicates they are popped). If not, ping pong ball!
