A pure substance that cannot be chemically broken down into simpler substances.
Condensing (or condensation or condense), I hope this helps.
Declarative knowledge refers to knowledge that can be expressed in words or symbols and encompasses facts, concepts, and information that one can declare or describe. It includes understanding and recalling information about "what" things are, such as rules, theories, and definitions. This type of knowledge is often contrasted with procedural knowledge, which is about knowing "how" to perform tasks or skills. Examples of declarative knowledge include knowing historical dates, scientific principles, or vocabulary definitions.
There are three definitions. A substance that produces hydroxide (OH-) ions in water. A substance that accepts a proton (H+ ion). An electron pair donor.
Reactivity is not a physical property because it's a characteristic of a chemical element or compound and is involved in chemical process.
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.

Intensional definitions describe the essential qualities or characteristics of a concept, while extensional definitions list specific examples or instances of the concept.
No. You have to change the number of protrons.(Changing the number of neutrons changes the isotope of the element, but it is still the same element. However, changing the number of neutrons will often result in instability, causing a radioactive decay sequence, which often results in a change in element.)
The mass number can vary without changing the identity of an element, as it represents the number of protons and neutrons in the nucleus. Conversely, changing the number of protons would change the identity of the element, as it defines the element's atomic number.
yes Generally, but language is always changing and new words are added as old one's are dropped continually. Usually they have the most used word meanings or most common definitions.
The atomic number of an element shows the number of protons that element has. Changing the number of neutrons creates a new isotope, and changing the number of electrons creates an ion. But changing the number of protons creates a different element.

The boiling temperature of an element can change by changing the pressure.
No. The number of protons is part of the fundamental characteristics of an element.
A term used to describe any element or compound is called a substance or substances.
"Economics is the study of how people relate to each other" is a statement that does not define economics.
Chemical properties describe how a substance interacts with other substances to form new chemical bonds or undergo chemical reactions. Physical properties, on the other hand, describe the characteristics of a substance that can be observed without changing its chemical identity, such as color, density, and melting point.
