Final answer:
Density (option D) is the property that is the same for both beakers containing water because it is an intensive property and does not depend on the volume of water present; it remains constant at 1.0 g/mL.
Step-by-step explanation:
When considering two beakers containing water, the property that will be the same for both samples is density. Density is an intensive property, meaning it does not depend on the amount of material present. Water has a density of 1.0 g/mL, and this value remains constant whether the water is in a small container or a large one. Therefore, considering two beakers of water, regardless of their volume, temperature, or color, their density will remain the same at 1.0 g/mL as long as the conditions, such as temperature and pressure, are the same.
