They will then predict the melting times for four and for sixteen ice cubes in water of the same temperature. Of the following, a skill that is prerequisite to making successful predictions for this experiment is the ability to: a) make accurate observations b) read a chart showing the data c) use a metric scale d) identify likenesses and differences ANSWER- a) make accurate observations Phases of Matter ANSWER- Solid, Liquid, Gas, Plasma What happens when matter heats up? ANSWER- The atoms are colliding faster and faster. There is also a relationship between the temperature, volume and pressure of gasses.
