 |  Matter And Its Composition 38 Flashcards |  Start |
 | What is matter defined as? |  Card: 1 / 38 |
| Matter is anything which occupies space or volume, has mass, and can be perceived by our senses. | Card: 2 / 38 |
| Which of the following states of matter has the least kinetic energy? A) Gas B) Liquid C) Solid D) Plasma | Card: 3 / 38 |
| C) Solid | Card: 4 / 38 |
| True or False: Liquids have a fixed shape and volume. | Card: 5 / 38 |
| False. Liquids have a fixed volume but do not have a fixed shape. | Card: 6 / 38 |
| Riddle: I can change from solid to gas without becoming liquid, often seen in ice and dry air. What am I? | Card: 7 / 38 |
| Sublimation | Card: 8 / 38 |
| The process of change from liquid to gas at any temperature below its boiling point is called ______. | Card: 9 / 38 |
| Evaporation | Card: 10 / 38 |
| What is Brownian motion? | Card: 11 / 38 |
| Brownian motion is the random motion of particles suspended in a fluid due to bombardment by fast-moving atoms or molecules. | Card: 12 / 38 |
| Fill in the blank: The heat energy required to convert 1 kilogram of solid into liquid at its melting point is called ______. | Card: 13 / 38 |
| Latent heat of fusion | Card: 14 / 38 |
| True or False: Gases can be compressed easily. | Card: 15 / 38 |
| True. | Card: 16 / 38 |
| What is the effect of increasing temperature on the rate of evaporation? | Card: 17 / 38 |
| Increasing temperature increases the rate of evaporation. | Card: 18 / 38 |

| Bose–Einstein condensate | Card: 20 / 38 |
| What is the law of conservation of mass? | Card: 21 / 38 |
| It states that mass can neither be created nor destroyed in a chemical reaction, and the total mass of reactants equals the total mass of products. | Card: 22 / 38 |
| Which state of matter has a definite shape and volume? A) Solid B) Liquid C) Gas D) Plasma | Card: 23 / 38 |
| A) Solid | Card: 24 / 38 |
| Fill in the blank: The process of change from solid to liquid is called ______. | Card: 25 / 38 |
| Melting | Card: 26 / 38 |
| True or False: The particles of a gas have a strong force of attraction between them. | Card: 27 / 38 |
| False. The force of attraction between gas particles is negligible. | Card: 28 / 38 |
| What phenomenon describes the hidden heat required to change a solid into a liquid? | Card: 29 / 38 |
| Latent heat of fusion | Card: 30 / 38 |
| Riddle: I am a state of matter, ionized and energetic, found in stars. What am I? | Card: 31 / 38 |
| Plasma | Card: 32 / 38 |
| What happens during condensation? | Card: 33 / 38 |
| Gas particles lose kinetic energy and come closer together to form a liquid. | Card: 34 / 38 |
| Which process occurs at a constant temperature when a liquid turns into a solid? | Card: 35 / 38 |
| Freezing | Card: 36 / 38 |
| What is the process called when a solid changes directly into a gas without passing through the liquid state? | Card: 37 / 38 |
| Sublimation | Card: 38 / 38 |
