1 Garrison wants to know why the shape of water changes when it goes through a state change. The model below shows how water changes as it melts. 4 The image shows the drawing a student made of ice molecules observed through an electron microscope. O- Is the student's drawing correct? A. Yes, because the molecules in the solid state are arranged randomly and move randomly Which question could BEST help understand why the shape of water changes when it turns from a solid to a liquid? A. Which model has the most water molecules? relative to each other. B. No, because the molecules in the solid state are arranged in ordered arrays and do not move much relative to each other. B. Which model has the largest water molecules? C. How can the color of the particles be described? C. No, because the molecules in the solid state are arranged in ordered arrays and move randomly relative to each other. D. How can the arrangement of the particles be described? D. Yes, because the molecules in the solid state are arranged randomly and do not move much 2 Which grouping of the three phases of bromine is listed in order of increasing average distance relative to each other. between bromine molecules? 5 How do the atoms of a solid move? A. gas, liquid, solid A. Atoms in a solid only shake back and forth in place. B. solid, liquid, gas C. liquid, solid, gas B. Atoms in a solid move freely and quickly. D. solid, gas, liquid C. Atoms in a solid move the same as in a liquid. D. Atoms in a solid do not move. 3 An unknown substance kept in a sealed container at STP had a density of 808 kg/m3. When the container was opened and the substance was exposed to room temperature, its density became 1.25 kg/m3. Which change did the substance most likely undergo? 6 When the pressure exerted on a confined gas at constant temperature is doubled, the volume of the gas is A. doubled. A. solid to liquid B. tripled. B. liquid to solid C. quartered. C. gas to liquid D. halved. D. liquid to gas
