2. Two liquids are poured into two cups. Cup A contains a colorless, odorless liquid. Cup B contains a colorless liquid with a strong odor. An ice cube floats in Cup A but sinks in Cup B. When heated, the liquid in Cup B boils at a much lower temperature than the liquid in Cup A. What kind of properties are used to compare the two liquids?
a. Chemical
b. Physical
c. Visible
d. Both chemical and physical
Physical
ice cube = physical
boiling temp = physical
color = physical and visual but not used
stink = chemical, something is reacting
Two forces are acting on a wheelbarrow. One force is pushing to the right and an equal force is pushing to the left. What can you say about the wheelbarrow's movement?
physical
Physical is the answer mate
Does anyone know the answers to the whole test?
The properties used to compare the two liquids are physical properties.
Explanation:
Physical properties are characteristics of a substance that can be observed or measured without changing the composition of the substance. In this scenario, we are comparing the color, odor, buoyancy of the ice cube, and boiling points of the liquids in Cup A and Cup B.
The fact that Cup A contains a colorless, odorless liquid while Cup B contains a colorless liquid with a strong odor is an example of a physical property. We can observe and distinguish the differences in the appearance and smell of the liquids without altering their chemical composition.
The buoyancy of the ice cube is another physical property used for comparison. The ice cube floats in Cup A but sinks in Cup B, indicating differences in density or specific gravity between the two liquids.
Lastly, the boiling points of the liquids in Cup A and Cup B are compared. It is mentioned that the liquid in Cup B boils at a much lower temperature than the liquid in Cup A. The boiling point is a physical property that indicates the temperature at which a substance changes from a liquid to a gas state.
Since all the properties used to compare the two liquids are physical properties that can be observed or measured without changing the composition of the substances, the answer is b. Physical.
