True/False and Fill-in-the-blank 1. The mass of atoms, their size, and how they are arranged determine the __________ of a substance. 2. True or false? The relationship between mass and volume in density can be expressed as D = mv2 3. True or false? A submerged object displaces a volume of liquid equal to the volume of the object. 4. The ________ of atoms, their size, and how they are __________ determine the density of a substance. 5. In a laboratory, the volume of a liquid is most commonly measured with a _____________ cylinder. 6. True or false? If you have two samples of the same substance, but one sample is larger than the other, the larger sample will have a greater density. 7. Hot water is ___________ dense than cold water because the molecules in hot water are ___________ apart. 8. True or false? A liquid will float if it is more dense than the liquid it is placed in. 9. The __________ of an object determines whether it will float or sink in another substance.

Sagot :

Answer:

1) Density

2) False

3) True

4) mass. arranged

5) graduated

6) False

7) Less, further

8）False

9) Density

Explanation:

1) Mass of atoms, size, and arrangement directly determine density of a substance.

2) Density = m/v,

3) Submerged objects must displace liquid equal to its volume because you are adding mass into a body of water

4) same as #1

5) Graduated cylinders are the most commonly used measurement tool for measuring volume

6) If it is the same substance it is equal in density. D=m/v, even if one sample is larger, both m and v increases

7) Hotter things have faster moving molecules so they are further apart. This causes the molecules to be less compact and thus less dense.

8) Liquids only float if it is less dense then the liquid it is placed on.

9) Density determins buoyancy.
