A student measures the mass of a dry stone correctly. An air bubble remains attached when the stone is submerged to measure its volume. How does the bubble affect the calculated density?
The measured volume is too large, so the density is too high.
The measured volume is too large, so the density is too low.
The measured volume is too small, so the density is too low.
The measured volume is too small, so the density is too high.
