Three 3.0 L sealed flasks , each at a pressure of 878 mmHg contain He, Ar, and Xe respectively. a) which of the flasks contain the greatest number of moles of gas? b) which of the flasks contain the greatest mass of gas? c) If He flask was heated and Ar flask was cooled, which of the three flasks would be at the highest pressure? d) If the temperature of the He was lowered while the Xe was raised, which of the three gases would have the greatest kinetic energy?

An experiment is conducted to see if cats preferred skim milk or 2% milk. a cup of skim milkwas put out for 5 kittens and then measured how much the kittens drank over the course of aday. following a cup of 2% milk was purout for the skittens and then masured how much thekittens drank over the course of a day. the same kittens were used and the milk was served atthe same temperature. it was discovered that the cats liked the 2% milk more than the skimmilk. what is the dependent variable in this experiment?
