An object has density 0.8 g/cm3 and is placed in water (1 g/cm3). What happens?
Answer and explanation
Correct answer: D. It floats
- Step 1: Compare the densities: 0.8 < 1. Step 2. An object less dense than the fluid is pushed up more than it weighs. Answer: It floats. Why not the others: Mass alone does not decide; only density does.
