Changes in States of Matter

Master the fascinating world of States of Matter and understand how substances transform through various phase changes!

States of Matter Video Watch the video and complete the questions below. Three of the four states of matter are mentioned in this video. Which one is left out? solid plasma liquid gas What is water made of? atoms molecules Both answers are correct. What does H2O stand for? 2 Hydrogen atoms bonded to 1 Oxygen atom. 1 Hydrogen atom bonded to 2 Oxygen atoms. 2 Hydrogen and Oxygen atoms bonded to each other. No answers are correct. Particle Behavior Match each state of matter of water with the correct description of its molecules. solid ice Particles vibrate but they do not move from their position. liquid water Particles move past each other but stay in contact. water vapor gas Particles move very fast and bounce away from each other. Which of the following substances can be a gas, liquid or solid? gold oxygen water All answers are correct. Particles of a substance _ when cooled and _ when heated. move slower / move faster lose energy / gain energy move closer together / move further apart All answers are correct. Phase Change Graph Watch this video and then label the blank graphs below. Phase Change Graph Label the graph correctly with the three main states of matter. solid liquid gas Phase Change Graph Label the diagram with the correct changes of state: condensation, freezing, vaporization, melting. condensation vaporization freezing melting This photo is an example of . . . evaporation. deposition. sublimation. condensation. This photo is an example of . . . evaporation. sublimation. deposition. condensation. This photo is an example of . . . evaporation. sublimation. deposition. condensation. What is the difference between sublimation and evaporation? The temperature of ice is . . . exactly zero degrees Celsius. zero degrees Celsius or higher. zero degrees Celsius or lower. None of these answers are correct. Match each word with its corresponding statement. freezing and melting point of water zero degrees Celsius boiling and condensation point of water 100 degrees Celsius What is the difference between vaporization and evaporation?
