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.

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.

The sound of a fire truck is loud. This is because fire trucks are equipped with powerful sirens and horns that emit a high volume sound. The loudness of the sound is necessary to alert people and clear the way for the fire truck to pass through traffic quickly and safely. Additionally, the loud sound helps to grab the attention of people in emergency situations and signal the presence of the fire truck.

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.

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.

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.

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.

An ambulance is typically associated with loud noises. When responding to an emergency, ambulances often use sirens and horns to alert other drivers and pedestrians. These loud sounds help to quickly grab attention and clear the way for the ambulance to reach its destination as quickly as possible.

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.

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.

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.

The answer is "loud" because a church's bell is typically designed to produce a strong, resonant sound that can be heard over a large distance. Bells are usually made of metal and are struck with a hammer, creating a loud and distinctive ringing sound. This is necessary in order to alert the community to important events such as religious services or emergencies.

The given answer "soft" is a suitable description for "breezing air" because it implies a gentle and gentle nature. When we think of a breeze, it is often associated with a light and soothing sensation, which aligns with the idea of softness.

A soft drink is a type of beverage that is typically in a liquid state. It is composed of various ingredients such as water, sweeteners, flavorings, and carbonation. Soft drinks are not solid or gaseous in nature, making the answer "liquid" the most appropriate choice.

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.

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.

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.

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.

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.

The given correct answer "soft" suggests that the chirping bird is producing a gentle and low sound. This implies that the bird's chirping is not loud or noisy, but rather soothing and quiet.

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.

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.

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.

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.
