The diagram below shows the different phase transitions that occur in matter. Three bars are shown labeled Solid, Liquid, and Gas. They are connected by arrows labeled 1 to 6. Arrow 1 points from liquid to gas; arrow 2 from solid to liquid, arrow 3 from solid to gas, arrow 4 from gas to liquid, arrow 5 from liquid to solid, and arrow 6 from gas to solid. Which statement best describes the process that arrow 1 represents? Molecules are speeding up as boiling occurs. Molecules are slowing to a stop while freezing. Molecules are slowing down during condensation. Molecules are vibrating in stationary positions. Mark this and return
