Matter And Its Properties Quiz Questions

Adding heat to a solid can increase its temperature and cause it to melt, changing it into a liquid. Similarly, adding heat to a liquid can increase its temperature and cause it to evaporate, changing it into a gas. This process is known as heating or thermal energy transfer.

A chemical change involves the transformation of one or more substances into different substances with different chemical properties. This transformation is brought about by a chemical reaction, where the bonds between atoms are broken and new bonds are formed. Therefore, it is correct to say that with a chemical change, a chemical reaction occurs.

The correct answer is "Anything that takes up space and has mass." This answer accurately describes matter as anything that occupies space and has mass. This definition is widely accepted in the field of physics and chemistry. Matter can exist in various forms, including solids, liquids, and gases, but the key characteristic is that it has both volume (takes up space) and mass.

Mass is a fundamental property of matter that refers to the amount of matter an object contains. It is a measure of the total number of atoms and molecules present in an object. The more mass an object has, the more matter it contains. Mass is different from weight, as weight is the force exerted on an object due to gravity. Therefore, the correct answer is "The amount of matter something has."

Gases are described as a state of matter that has mass but no shape. They fill and take the shape of a container, which means they have the ability to expand and contract. Air is a mixture of gases, which indicates that gases can be found in the atmosphere and are present everywhere. This explanation accurately describes the characteristics of gases and their behavior.

Solids cannot change their shape because they have a fixed volume and their particles are tightly packed together. Unlike liquids and gases, solids do not flow or take the shape of their container. The particles in a solid are held in a fixed position by strong forces of attraction, which prevents them from moving freely and changing their shape. Therefore, it is true that solids cannot change their shape.

The four states of matter are solid, liquid, gas, and plasma. Solids have a definite shape and volume, with particles vibrating in place. Liquids have a definite volume but take the shape of their container, with particles that can move past each other. Gases have no definite shape or volume and fill their container, with particles that move freely. Plasma is a high-energy state with stripped electrons, found in stars and lightning.

Matter can undergo physical changes, where its physical properties such as shape, size, or state may change, but its chemical composition remains the same. On the other hand, matter can also undergo chemical changes, where its chemical composition is altered, resulting in the formation of new substances with different properties. Therefore, the given answer correctly identifies the two types of changes that can occur in matter.
