2.) Write out an experimental procedure to qualitatively compare the boiling behavior of liquids. Next, you will write out an experimental procedure to quantitatively compare the boiling points, and then you will carry out one or both procedures and record your observations. Can one of you guys help me with this question, I don't understand it.

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20

When you see distant streetlights through smog, they look dimmer and redder than they do normally. but when you see the same streetlights through fog or falling snow, they look dimmer but not redder. use your knowledge of the interstellar medium to discuss the relative sizes of the particles in smog, fog, and snowstorms compared to the wavelength of light.
