1. You are given a quantity of a volatile liquid substance and asked to determine its molecular weight. To do that, you place a sample of the liquid in a 200.0-mL flask and submerge the flask in a boiling water to vaporize all of the liquid. The vapor fills the flask and the excess escapes,. Now you cool the flask so that all the vapor in it condenses, and you weigh the flask and liquid. After you subtract the mass...

a) A mildly restored ‘Knight-Rider’ 1989 Pontiac Trans Am GTA powered by a 5.7 litre V8 can do a quarter mile S from rest in a time t of about 15 seconds. Using distance: S=a t2 /2 , force: F=ma and work: W=FS, calculate the amount of work (energy) in kJ required to do the standing quarter mile given that the mass (m) of this Trans Am is 3,500 pounds. Assume that the acceleration (a) is constant. (This is not...
