A helium-filled weather balloon of a spherical shape has a 1.0 m radius at liftoff where air pressure is 1.00 atm and the temperature is 290 K. When airborne, the temperature is 230 K, and its radius expands to 1.35 m. What is the pressure at the airborne location in unit of atm?

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.
