Graph below compares the volume occupied by 100 g of liquid water and 100 g of water vapor. a bar graph is shown with the title, volume occupied. the y axis title is, volume. the x axis title is, substance. there are two markings on the x axis. one is marked x and the other is marked y. the bar above x is far higher than the bar above y. which statement best describes the two substances? particles are farther apart in liquids so substance y is liquid water. particles are closer together in liquids so substance x is liquid water. particles are closer together in gases so substance y is water vapor. particles are farther apart in gases so substance x is water vapor.
