Answer:
If volume remains the same while the mass of a substance increases, the density of the substance will increase.
Step-by-step explanation:
Mathematically D = m/V tells us that density is directly proportional to the mass and inversely proportional to volume. Therefore if the mass increases the density will also increase.
Analytically, density is mass per unit of volume. So if you had 500 kg of mass packed in a one cubic meter box, clearly your density would 500 kg per cubic meter. Now if you added another 500 kg of mass in that same box(volume unchanged) the density goes up to 1000 kg per cubic meter. So If volume remains the same while the mass of a substance increases, the density of the substance will increase.
