Question

click to select the correct answers. click again to unselect answers. leave the incorrect answers unselected. density and mass are physical properties of matter that affect other characteristics such as weight and how sinkable objects are. density is the amount of mass found in a given space. which statements are true about mass and/or density? (choose 3) a a balloon inflated with air has less mass than a marble b a basketball - sized balloon filled with air has more density than a baseball - sized balloon filled with sand c a marble has more density than a balloon inflated with air. d objects with low density tend to sink more quickly than those with high density e if two balls are placed in a tank of water, the one with more density will sink faster. f the more dense an object is, the lower its mass will be.

Explanation:

• Option A: Air has very low mass, and a marble (solid, denser material) has more mass than a balloon with air. So this is true.
• Option B: Sand is much denser than air. A balloon with sand (even smaller size) will have higher density than a balloon with air (larger size). So this is false.
• Option C: A marble is a solid (usually made of dense materials like glass/stone) and air in a balloon is low - density. So marble has more density. This is true.
• Option D: Objects with low density are more likely to float, while high - density objects sink faster. So this is false.
• Option E: In a fluid (like water), an object with higher density relative to the fluid will sink, and a more dense object will sink faster. This is true.
• Option F: Density is mass per unit volume ($

ho=\frac{m}{V}$). For a given volume, more dense objects have more mass. So this is false.

Answer:

A. A balloon inflated with air has less mass than a marble
C. A marble has more density than a balloon inflated with air.
E. If two balls are placed in a tank of water, the one with more density will sink faster.
