TRANSCRIPT
If a substance has a density that is higher than a liquid’s density, then it will sink
If a substance has a density that is lower than the liquid’s density, then it will float
The stone and glass stopper sink in water because it has a higher density than water
The ice cube and cork floats in water because it is less dense than water
ConclusionCork & ice cube have the lowest densityStone & glass stopper have highest density
Table 4 shows four substances with their densities.
Substances Density (g/cm3)
W 0.25
X 0.95
Y 0.55
Z 1.50
