- upper will śink because it is more dense than water.However the diet soda is less dense than the regular. 30. Density can be calculated by dividing the mass of an object by its volume. Water has a density of 1g/ml. If an object's density is greater than 1 g/ml it will sink and if its density is less than 1g/ml it will float. Object A has a mass of 40g and a volume of 30mL and object B has a mass of 15 g and a volume of 20 mL. What will happen when both objects are placed in water? A. Object A will float because its density is less than water B. Object B will sink because its density is greater than water C. Object A will sink because its density is greater than water D. Objects A and B will both float because their density is the same as water NOV 8.1.covert 7712 cubic centimeters to liters 2.covert 31.7 quarts to littersUsing my chart attached which bags lost mass? Which molecule directly caused the decrease in mass? Describe what direction that molecule moved (in or out of the bag) and why that molecule moved in that specific direction.

What is the starting volume of water in the graduated cylinder? B. Place the apple into the cylinder. What is the volume in the cylinder how? The water rises in the cylinder because it is displaced, or pushed upward, by the apple. The amount of displaced water is equal to the volume of the apple. C. What is the volume of the apple? (Use the Object volume to check.) Note: Milliliters (mL) are used for liquid volumes, while cubic centimeters (cm") are used for solids. One mL is the same volume as one cm". The apple's volume is measured in cm". Get the Gizmo ready: Activity A: • Replace all objects on the shelf. • Be sure the liquid in the beaker is Water. Sink or float?
