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
Toasting a marshmallow too long in a campfire causes it to turn black. This change in color is an indication of a chemical reaction taking place. The heat from the fire causes the sugars in the marshmallow to undergo a process called caramelization, where they break down and form new compounds. This chemical change results in the blackened appearance of the marshmallow. The heat from the fire also causes the marshmallow sugars to react with oxygen in the air in a combustion reaction, turning the marshmallow black. Therefore, the blackening of a marshmallow when toasted too long is a chemical property.Rate this question:

Hydrogen peroxide dental strips will make your teeth whiter.
- A.
Physical Property
- B.
Chemical Property
Correct Answer
B. Chemical PropertyExplanation
Hydrogen peroxide dental strips will make your teeth whiter because hydrogen peroxide is a bleaching agent that can break down the stains and discoloration on the surface of the teeth. This process involves a chemical reaction where the hydrogen peroxide oxidizes the pigments in the stains, resulting in a brighter and whiter appearance.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.

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:

Mass is..... (check all that apply)
- A.
Expressed in kilograms
- B.
The quantity of matter contained in the object
- C.
Dependent on gravity
Correct Answer(s)
A. Expressed in kilograms
B. The quantity of matter contained in the objectExplanation
Mass is a physical property of matter that is expressed in kilograms. It represents the amount of matter contained in an object and is independent of gravity. Therefore, the correct answers are "expressed in kilograms" and "the quality of matter contained in the object".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:
