A12,000-n car is raised using a hydraulic lift, which consists of a u-tube with arms of unequal areas, filled with incompressible oil with a density of 800 kg/m3 and capped at both ends with tight-fitting pistons. the wider arm of the u-tube has a radius of 18.0 cm and the narrower arm has a radius of 5.00 cm. the car rests on the piston on the wider arm of the u-tube. the pistons are initially at the same level. what is the force that must be applied to the smaller piston in order to lift the car after it has been raised 1.20 m? you may neglect the mass of the pistons.

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.
