Physical and Chemical Properties Questions and Answers
- 1.
A marshmallow turns black when toasted too long in a campfire.
- A.
Physical Property
- B.
Chemical Property
Correct Answer
B. Chemical PropertyExplanation
The marshmallow turning black is a sign of a chemical change, specifically combustion. The heat from the campfire causes the sugars in the marshmallow to react with oxygen, producing carbon and other byproducts, resulting in the black color.Rate this question:

Hydrogen peroxide dental strips will make your teeth whiter.
- A.
Physical Property
- B.
Chemical Property
Correct Answer
B. Chemical PropertyExplanation
The whitening effect of hydrogen peroxide dental strips is due to a chemical reaction. Hydrogen peroxide acts as an oxidizing agent, breaking down the chromogens (color-causing compounds) that stain teeth. This chemical change alters the structure of the chromogens, making them less visible and resulting in whiter teeth.Rate this question:

A log of wood is chopped up with an axe into smaller pieces of wood.
- A.
Physical Property
- B.
Chemical Property
Correct Answer
A. pHysical PropertyExplanation
The act of chopping a log of wood into smaller pieces does not change the chemical composition or identity of the wood. It only alters its physical appearance and shape. Therefore, this process is an example of a physical property, as it does not involve any chemical reactions or changes in the fundamental nature of the wood.Rate this question:

If you wash your jeans with chlorine bleach, they will fade.
- A.
Physical Property
- B.
Chemical Property
Correct Answer
B. Chemical PropertyExplanation
This statement suggests that washing jeans with chlorine bleach will cause them to fade. This is an example of a chemical property because it describes how the jeans will react with the chlorine bleach, resulting in a change in their color. Chemical properties describe how a substance interacts with other substances and can result in a chemical change.Rate this question:

Blue color
- A.
Physical Property
- B.
Chemical Property
Correct Answer
A. pHysical PropertyExplanation
Blue color is a physical property because it can be observed and measured without changing the chemical composition of the substance. Physical properties are characteristics that can be observed or measured without altering the substance's identity. In this case, the color of an object can be determined by simply looking at it, without any chemical reactions taking place.Rate this question:

Density
- A.
Physical Property
- B.
Chemical Property
Correct Answer
A. pHysical PropertyExplanation
Density is a physical property of a substance, which refers to the amount of mass per unit volume. It is a characteristic property that can be used to identify and classify substances. Density is a measure of how closely packed the particles are in a substance, and it remains constant regardless of the amount of the substance present. Therefore, density is a physical property that can be measured and used to distinguish different substances from each other.Rate this question:

- 7.
Which of the following is a chemical property of a substance?
- A.
Density
- B.
Melting point
- C.
Flammability
- D.
Color
Correct Answer
C. FlammabilityExplanation
Flammability refers to the ability of a substance to burn or ignite, which involves a chemical reaction with oxygen. The other options are physical properties, which can be observed or measured without changing the substance's chemical composition.Rate this question:

Reacts with water to form a gas
- A.
Physical Property
- B.
Chemical Property
Correct Answer
B. Chemical PropertyExplanation
This statement suggests that the substance being referred to undergoes a chemical reaction when it comes into contact with water, resulting in the formation of a gas. This indicates that the substance has a chemical property, as it exhibits a characteristic behavior when it reacts with water.Rate this question:

- 9.
Which of the following indicates a physical change rather than a chemical change?
- A.
Iron rusting
- B.
Paper burning
- C.
Ice melting
- D.
Wood rotting
Correct Answer
C. Ice meltingExplanation
A physical change alters the form or appearance of a substance but does not change its chemical composition. When ice melts, it changes from a solid to a liquid state, but it is still water (H2O). The other options involve chemical changes, where new substances are formed:
Iron rusting: Iron reacts with oxygen to form iron oxide (rust).
Paper burning: Paper undergoes combustion, reacting with oxygen to produce ash, carbon dioxide, and other products.
Wood rotting: Wood decomposes due to the action of microorganisms, breaking down into simpler substances.Rate this question:

Weight is dependent on gravity
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Weight is dependent on gravity because weight is the force exerted on an object due to the gravitational pull of the Earth (or any other celestial body). The weight of an object can vary depending on the strength of gravity. On Earth, the weight of an object is directly proportional to its mass and the acceleration due to gravity. This means that if the gravity is stronger, the weight of an object will be greater, and if the gravity is weaker, the weight will decrease. Therefore, weight is indeed dependent on gravity.Rate this question:

The ability of iron to rust when exposed to air and moisture. Is this a chemical or physical property?
- A.
Chemical Property
- B.
Physical Property
Correct Answer
A. Chemical PropertyExplanation
Rusting is a chemical property of iron. Chemical properties involve the substance's ability to undergo chemical changes or reactions, leading to a transformation in its composition. Iron undergoes an oxidation reaction in the presence of air and moisture, which causes the formation of iron oxide, or rust, indicating a chemical change.Rate this question:

The ability of paper to burn when exposed to an open flame. Is this a chemical or physical property?
- A.
Chemical Property
- B.
Physical Property
Correct Answer
A. Chemical PropertyExplanation
Burning is a chemical property of paper. When paper combusts, it undergoes a chemical reaction with oxygen, resulting in the formation of new substances like ash and smoke. This transformation indicates a chemical change.Rate this question:

The solubility of sugar in water. Is this a chemical or physical property?
- A.
Chemical Property
- B.
Physical Property
Correct Answer
B. pHysical PropertyExplanation
Solubility is a physical property. It describes how a substance dissolves in another without changing its chemical composition. In the case of sugar dissolving in water, it is a physical change as the sugar molecules remain unchanged.Rate this question:

Which of the following is a chemical property of a substance?
- A.
Melting point
- B.
Density
- C.
Reactivity with acid
- D.
Boiling point
Correct Answer
C. Reactivity with acidExplanation
Reactivity with acid is a chemical property because it describes how a substance undergoes a chemical change when it interacts with an acid, resulting in the formation of new substances. In contrast, melting point, density, and boiling point are physical properties, as they describe the characteristics of a substance that can be observed or measured without changing its chemical identity. Understanding these distinctions is crucial in the study of material properties.Rate this question:
