Unformatted text preview: happened while keeping all other variables constant. a) If the pressure of a system increases, the temperature must have increased the number of moles must have decreased the volume must have increased b) If the temperature of a system decreases, the number of moles must have decreased the volume must have decreased the pressure must have increased c) If the volume of a system decreases, the temperature must have increased the number of moles must have decreased the pressure must have decreased 4. Indicate whether each of the following molecules is polar (p) or nonpolar (n). Your response should be a three letter word consisting of the letters p and n. For example, a response of npn would indicate that only CH 2 F 2 , the second molecule, is polar. Note: remember that you must consider the three dimensional structure of the molecules to answer the question. Answer: ppp...
