A 64 g ball is shot into the barrel of a spring-gun with a speed of 24 m/s. The sprig-gun has a mass of 280 g and is initially at rest on a frictionless surface. The ball sticks in the barrel at the point of maximum compression of the spring. Assume that friction between the ball and the barrel is negligible. Note that momentum is conserved as the ball becomes stuck in the spring-gun because the net-force on the system containing both the ball and the spring-gun is zero. A ball is fired into the barrel of a spring-gun. What is the change in kinetic energy of the ball and spring-gun

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
