During a macroscale fractional distillation to separate cyclohexane and toluene (25 ml each), water was not running through the condenser until we reach about 15 ml of distillate. the first drop of distillate was observed at 85 centigrades. the distillation curve didn't show a clear first plateau (temperature vs volume of distillate). it looks like a simple distillation curve. we didn't obtain the first drop until 85 centigrades because of the condensator issue? why the lack of plateau (slightly steep curve) has persisted after connecting the water source. you!

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
