A substance that changes readily into vapor without heating is called a volatile substance. Examples include alcohol and acetone.
The expansion of matter upon heating is an example of a physical change. This is because the substance undergoes a change in form or appearance without forming a new substance.
Heating copper sulfate crystals is a physical change because it only involves a change in state from solid to liquid or gas, without altering the chemical composition of the substance. Chemical changes involve the rearrangement of atoms to form new substances with different properties.
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
One example of an element that sublimes on heating is iodine. When solid iodine is heated, it directly changes into a gas without passing through a liquid phase.
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
Readily absorbed means that a substance can be easily taken in or assimilated by the body without much effort.
Magnetism, dissolving, sifting (might count as filtering).
Melting: The substance changes from a solid to a liquid as heat is applied. Freezing: The substance changes from a liquid to a solid as it loses heat. Evaporation: The substance changes from a liquid to a gas as it is heated. Condensation: The substance changes from a gas to a liquid as it cools. Sublimation: The substance changes directly from a solid to a gas without going through a liquid phase.

It sublimes
One common substance that sublimes on heating is dry ice, which is solid carbon dioxide. When heated, dry ice transitions directly from a solid to a gas without passing through the liquid phase.
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.

One substance that does that is carbon dioxide.
These physical changes doesn't influence the chemical formula of the substance.
