Question

what is the densest liquid shown? which liquid is less dense than liquid e? what is the least dense object shown? what is the total number of layers of solid, liquid, and gas?

Explanation:

Step1: Identify layers

There are 4 layers - air, liquid F, liquid E, liquid D.

Step2: Determine least - dense object

Object A is floating on liquid F, so it is the least - dense among the objects shown.

Step3: Find liquid less dense than E

Liquid F is above liquid E, so liquid F is less dense than liquid E.

Step4: Determine densest liquid

Liquid D is at the bottom, so it is the densest liquid.

Answer:

1. Total number of layers: 4
2. Least - dense object: A
3. Liquid less dense than E: F
4. Densest liquid: D
