- 4. factors or variables in an experiment that is intentionally kept constant so that it does not affect the outcome
- 6. The ratio of mass to volume for a substance.
- 9. properties are non-numeric characteristics of an object or phenomenon that are observed using the senses, such as color, texture, smell, and taste
- 11. refers to the ability of a substance (solute) to dissolve in a solvent to form a homogeneous mixture called a solution
- 12. a variable whose value depends on that of another.
- 15. change a change that alters a substance's appearance or form without changing its chemical identity
- 17. a state of matter characterized by a definite shape and volume, as its constituent particles are tightly packed and can only vibrate in fixed positions.
- 19. change a process where a substance transforms into a new substance with different properties, occurring through a chemical reaction
- 20. method is the application of scientific knowledge for practical purposes
- 22. Anything that has rest mass and volume and takes up space and it is made of particles.
- 24. characteristics of matter that do not change regardless of the amount of matter present
- 29. a physical property of matter that depends on the amount of substance present, meaning its value changes proportionally with the size or quantity of the sample
- 30. a state of matter where a gas of bosonic atoms is cooled to temperatures near absolute zero, causing them to lose their individual identities and occupy a single, low-energy quantum state
- 32. a mixture that does not have a uniform composition
- 33. a proto-science and philosophical tradition that existed before modern chemistry, primarily seeking to transform base metals into gold and discover an elixir of life
Down
- 1. the basic unit of a chemical element. A fundamental piece of matter.
- 2. a metal made by combining two or more metallic elements, especially to give greater strength or resistance to corrosion.
- 3. is a group of atoms bound together.
- 5. a state of matter with a definite volume but no fixed shape, meaning it flows and takes the shape of its container
- 7. a combination of two or more substances that are not chemically bonded together
- 8. any type of entity that is part of the observable universe, is measurable, and has a space-time location compatible with the laws of nature.
- 10. proposed by John dalton in 1808, states that all matter is made of tiny, indivisible particles called atoms
- 13. often called the "fourth state," that consists of a superheated, ionized gas containing ions, electrons, and neutral atoms
- 14. encompasses the systematic study of the structure and behaviour of the physical and natural world through observation and experiment
- 16. statement or question that is in question, yet to be proven
- 18. a state of matter in which particles are separated by large distances and move randomly and rapidly, colliding with each other and the container walls.
- 21. a variable whose variation does not depend on that of another.
- 23. Capacity of a material to deform permanently (e.g., stretch, bend, or spread) in response to stress.
- 25. a type of matter or substance that can't be broken down into other substances.
- 26. The scientific study of matter’s properties and behaviour is known as chemistry.
- 27. a mixture in which the components are uniformly distributed, resulting in a single phase with a consistent composition and appearance throughout
- 28. was a greek philosopher that first proposed that all matter is composed of tiny, indivisible, and indestructible particles called "atoms" in 400 BC
- 31. is the application of scientific knowledge for practical purposes
