Question
Place a strip of tape lengthwise on the bottle or jar, as shown in Figure 1. Half-fill the bottle or jar with either oil-and-vinegar–type salad dressing or equal amounts of vegetable oil and water or vinegar. Use a pen to mark a line on the tape at the top of each layer. Measure and record the height of each layer (the distance between the layer’s bottom and its top). What observation(s) allows you to determine which substance constitutes the top layer and which one the bottom? What general property of substances is responsible for this positioning? Explain.

What observation(s) allows you to determine which substance constitutes the top layer and which one the bottom? What general property of substances is responsible for this positioning? Explain.Explanation / Answer
Density is the main factor to determine which substance constitutes the top layer and which one the bottom.water having high density constitutes bottom layer and due to having less density than water ie,vegetable oil will constitute top layer .
