Matter is everywhere. It exists in different forms
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Matter is indeed everywhere and exists in various forms. It can be found in the solid, liquid, and gas states, as well as in plasma and Bose-Einstein condensates. Matter makes up everything around us, including the objects we see and touch, the air we breathe, and even the stars and planets in the universe. Therefore, the statement "Matter is everywhere. It exists in different forms" is true.Rate this question:

Matter has mass and occupies space.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because matter is anything that has mass and takes up space. Mass refers to the amount of matter in an object, and space refers to the physical dimensions that matter occupies. Therefore, all objects, whether they are solid, liquid, or gas, have mass and occupy space, making the statement true.Rate this question:

It may be round, square, triangular or rectangular.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement suggests that an object can have different shapes such as round, square, triangular, or rectangular. Since this is a general statement that does not specify any particular condition or limitation, it can be considered true.Rate this question:

It may also come in different sizes. Some are bigger than others.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement suggests that the subject being referred to can come in different sizes, with some being bigger than others. This implies that there is variability in the size of the subject, supporting the statement that it may come in different sizes. Therefore, the correct answer is true.Rate this question:

- 5.
Solid has definite size and shape.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Solid has definite size and shape because the particles in a solid are closely packed and have strong intermolecular forces holding them together. This arrangement results in a fixed shape and volume for solids, as they cannot be compressed or easily deformed. Unlike liquids or gases, solids maintain their structure and occupy a specific amount of space. Therefore, it is true that solids have a definite size and shape.Rate this question:
-
- 6.
Gas can be seen and touched.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Gas cannot be seen or touched because it is made up of particles that are widely spread out and do not have a definite shape or volume. Unlike solids and liquids, gases are invisible and do not have a physical presence that can be felt or sensed by touch. Therefore, the statement that gas can be seen and touched is incorrect.Rate this question:

Liquid has its own shape.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Liquids do not have their own shape. They take the shape of the container they are poured into. Unlike solids, which have a fixed shape, liquids are fluid and can flow and change shape. Therefore, the statement "Liquid has its own shape" is incorrect.Rate this question:
-
- 8.
Mass is the amount of material an object has.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Mass is indeed the amount of material an object has. It is a fundamental property of matter and is measured in units such as kilograms or grams. Mass is different from weight, which is the force exerted on an object due to gravity. Mass remains constant regardless of the location, while weight can vary depending on the strength of the gravitational field. Therefore, the statement "Mass is the amount of material an object has" is true.Rate this question:
-
- 9.
Matter has weight.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Matter has weight because weight is the force exerted on an object due to gravity. All objects, including matter, are subject to the gravitational pull of the Earth or other celestial bodies, which results in a measurable weight. Weight is a property of matter and can be measured using a scale or other weighing devices. Therefore, it is true to say that matter has weight.Rate this question:
-
- 10.
Gases can also flow.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Gases can flow because they have the ability to move freely and spread out in any direction. Unlike solids and liquids, which have a fixed shape and volume, gases can expand and fill the space available to them. This is due to the high kinetic energy of gas particles, which allows them to move around and collide with each other, causing the gas to spread out and flow. Therefore, it is true that gases can flow.Rate this question:

Cap
- A.
Solid
- B.
Liquid
- C.
Gas
Correct Answer
A. SolidExplanation
The term "cap" does not provide enough information to determine the state of matter. However, out of the three options given, "solid" is the only state of matter that can be associated with a cap. A cap is typically made of a solid material, such as plastic or metal, and does not change its shape or volume easily. Therefore, "solid" is the most appropriate answer based on the given options.Rate this question:

Smoke from a vehicle.
- A.
Solid
- B.
Liquid
- C.
Gas
Correct Answer
C. GasExplanation
When smoke is emitted from a vehicle, it is in the form of gas. Smoke is formed when fuel or oil is incompletely burned, resulting in tiny particles and gases being released into the air. These particles and gases form a visible cloud that we perceive as smoke. Since smoke is composed of gas, it can easily disperse and mix with the surrounding air.Rate this question:

Air freshener
- A.
Solid
- B.
Liquid
- C.
Gas
Correct Answer
C. GasExplanation
Air fresheners are typically in the form of a gas. They are designed to release pleasant scents into the air, and this is achieved by evaporating the liquid or solid fragrance contained within the air freshener. Once the fragrance is evaporated, it becomes a gas that can be dispersed in the air, providing a fresh and pleasant smell. Therefore, the correct answer is gas.Rate this question:

Mango juice
- A.
Solid
- B.
Liquid
- C.
Gas
Correct Answer
B. LiquidExplanation
Mango juice is a liquid because it has a definite volume but no definite shape. It can flow and take the shape of its container. Liquids have particles that are close together but can move past each other, allowing them to flow. In the case of mango juice, it is made by extracting the juice from mangoes, resulting in a liquid form that is commonly consumed.Rate this question:

Clock
- A.
Solid
- B.
Liquid
- C.
Gas
Correct Answer
A. SolidExplanation
The given options "solid, liquid, gas" are states of matter. Among these options, "solid" is the correct answer because it is the state of matter that has a definite shape and volume. Solids have tightly packed particles that vibrate in place, giving them a fixed shape and volume.Rate this question:
-
- 16.
Book
- A.
Solid
- B.
Liquid
- C.
Gas
Correct Answer
A. SolidExplanation
A book is a solid object. Solids have a definite shape and volume, and their particles are tightly packed together. A book maintains its shape and does not flow or change its volume when subjected to external forces. Therefore, the correct answer is solid.Rate this question:

Air inside the balloon
- A.
Solid
- B.
Liquid
- C.
Gas
Correct Answer
C. GasExplanation
The air inside the balloon is in the form of a gas. Gases have particles that are spread out and move freely, which allows them to fill the space they are in. In the case of a balloon, the air particles fill the balloon and exert pressure on its walls, causing it to inflate. This is why gas is the correct answer in this context.Rate this question:

Water may change into this when heated long enough.
Correct Answer
gasExplanation
When water is heated for a prolonged period, it undergoes a phase change and transforms into gas. This is known as water vapor or steam. The increase in temperature causes the water molecules to gain energy and move faster, eventually breaking the intermolecular bonds and escaping into the air as a gas. This phase change from a liquid to a gas is a result of the water molecules transitioning from a more ordered state to a more disordered and spread-out state.Rate this question:
