Density/layers QuizStarted: Nov 2 at 1:02pmQuiz InstructionsFlag question: Question 1Question 10.8 ptsWhy does ice float on water?Group of answer choicesIt is colder than waterIt is less dense than waterIt is lighter than waterIt is harder than waterFlag question: Question 2Question 20.8 ptsGroup of answer choicesoilwatercorn syrupalcoholFlag question: Question 3Question 30.8 ptsGroup of answer choicesBecause the oil is less dense it rises to the surface, making the clean up easier if the clean up crew acts fastBecause the oil is most dense it rises to the surface, making the clean up easier if the clean up crew acts fast.Because the oil is the most dense it will sink and make the clean up hard.Because the salt water is the least dense, it will rise to the surface and mix with the oil.Flag question: Question 4Question 40.8 ptsUse the image to answer the following questionWater has a density of 1 g/mL therefore we can assume that…Group of answer choicesThe milk is more dense than water.The honey is less dense than waterThe dish soap is less dense than water.The rubbing alcohol is more dense than waterFlag question: Question 5Question 50.8 ptsLiquids that float on top of other objects are less dense then the objects they are on top of.Group of answer choicesTrueFalseFlag question: Question 6Question 60.8 ptsEarth's interior is divided into layers.
