Answer: (3) Students B and C have their beakers filled to the same level. Therefore, the volumes of water overflowing from their beakers will be the same (VB = VC). Student A has his beaker filled to a level that is a little lower than the levels of water present in the beaker belonging to students B and C. Therefore, the volume of water overflowing from his beaker will be less than the volumes of water overflowing from the beakers belonging to students B and C.
