Density is described as crucial for determining whether an object in a fluid will:
ASink or float
BHeat or cool
CGlow or fade
DMelt or freeze
Answer & Solution
Correct answer: A. Sink or float
1. Density decides how an object sits in a fluid.
2. Density is the mass per unit volume of a substance or object.
3. It is crucial in determining whether an object sinks or floats in a fluid.
4. The comparison is between the object's density and the fluid's.
