Solid
Yes, true steam (you cannot see it) is matter in the gas form.
Anti- Matter
Yes, matter can be something that you can not see. This is because one form of matter is gas, which can not be seen.
An atom A fundamental particle
The abstract noun form of the verb to 'classify' is classification.
The law of conservation of matter is the law that says that matter cannot be created or destroyed, but can only change form
Aristotle is often credited with the concept that form and matter are inseparable in his philosophy of hylomorphism. The idea is that form and matter are two essential components that make up physical objects, with form providing the structure and organization, and matter providing the substance. Thus, according to Aristotle, form and matter are interdependent and cannot exist without one another.
To classify a change as reversible or irreversible, consider whether the original state can be restored. Reversible changes, such as melting ice or boiling water, can be undone, allowing the substance to return to its initial form. In contrast, irreversible changes, like burning wood or baking a cake, result in new substances that cannot revert to their original state. Thus, the classification depends on the ability to reverse the change.
No, substance is not the simplest form of matter; it is a form of matter that has a specific composition and distinct properties. The simplest form of matter is an element, which cannot be broken down into simpler substances through chemical means. Elements consist of atoms, which are the basic building blocks of all matter. Therefore, while substances are made up of elements, they represent a more complex arrangement of matter.
The principle that matter cannot be created or destroyed, only transformed from one form to another, is known as the Law of Conservation of Mass. This fundamental principle is a cornerstone of the field of chemistry and is supported by numerous scientific observations and experiments.
None, energy cannot be made or destroyed. It can only change form. The energy you would get from any organic matter is already in the matter. The energy is not being "made". It is just changing form. All matter is just energy.
23/20 is in its simplest form: it cannot be simplified.
