Question

two substances are placed in a flask.
substance a has a density of 4 g/l.
substance b has a density of 6 g/l.
substance a will dropdown with sink, float

Explanation:

Step1: Recall density principle

In a mixture of two substances, the one with lower density floats on the one with higher density.

Step2: Compare densities

Substance A: \( 4 \, \text{g/L} \), Substance B: \( 6 \, \text{g/L} \). Since \( 4 < 6 \), Substance A is less dense than B.

Step3: Determine behavior

Less dense substance floats on more dense substance. So Substance A will float.

Answer:

Float
