1.1 Physical Properties

Question 1

Which physical property can be measured?

Revolt · Accepted Answer

B: density

Question 2

Which statement explains why sugar dissolves easily in water, but sand does not?

Revolt · Accepted Answer

D: Sugar has a greater solubility than sand.

Question 3

Describe all of the forces acting on the ice cream in the root beer float. Relate these forces to the fact that the ice cream is floating.

Revolt · Accepted Answer

There are two primary forces acting on the ice cream: gravity and buoyancy. The force of gravity pulls the ice cream downward toward the center of the Earth. The buoyant force, exerted by the root beer, pushes the ice cream upward. Because the ice cream is floating and not sinking or rising further, these two forces are balanced (equal in magnitude and opposite in direction), resulting in a net force of zero. This occurs because the ice cream is less dense than the root beer.

Question 4

Gabriel accidently drops a glass on the kitchen floor, and it shatters. Which statements describe the physical change that has occurred? Check all that apply.The shape of the glass has changed.The identity of the glass has changedThe mass of the glass has changed.The size of the glass has changed.The density of the glass has changed.

Revolt · Accepted Answer

A: The shape of the glass has changed.; D: The size of the glass has changed.
