184.108.40.206: Substances can undergo physical changes which do not change the composition or the total mass of the substance in a closed system.
220.127.116.11.2: Describe how mass is conserved during a physical change in a closed system.
18.104.22.168.3: Use the relationship between heat and the motion and arrangement of particles in solids, liquids and gases to explain melting, freezing, condensation and evaporation.
22.214.171.124: The motion of an object can be described in terms of speed, direction and change of position.
126.96.36.199.1: Measure and calculate the speed of an object that is traveling in a straight line.
188.8.131.52.2: For an object traveling in a straight line, graph the object?s position as a function of time, and its speed as a function of time. Explain how these graphs describe the object?s motion.
