A student has two blocks of the same size. Block A has a mass of 100 grams and Block B has a mass of 50 grams. Which statement best explains why Block A is denser than Block B?, Block A is made of a different material that is always denser, Block A is larger than Block B, Block A weighs more because it is older, Block A has more mass packed into the same volume as Block B, If you have a substance with a density of 2 g/cm³, what does this measurement tell you?, The substance will always float in water, The substance takes up 2 cubic centimeters of space, Every 1 cubic centimeter of the substance has a mass of 2 grams, The substance weighs 2 grams total, A rock has a mass of 60 grams and a volume of 20 cm³. What is the density of the rock?, 0.33 g/cm³, 1,200 g/cm³, 80 g/cm³, 3 g/cm³, Why does ice float on top of water even though ice is made of frozen water?, Ice contains air pockets that make it float, Ice has a lower density than liquid water, so it floats, Ice is lighter in color than water, Ice is always colder and cold things float, A student measures a metal cube and finds it has a volume of 8 cm³ and a mass of 72 grams. If the student cuts the cube in half, what would be the density of one of the pieces?, 9 g/cm³, 4.5 g/cm³, 18 g/cm³, 36 g/cm³.
