If two objects have the same volume but one has a greater mass, the one with the greater mass
has a higher density
New cards
25
If you cut a wooden block in half, each half would have
the same density as the original piece
New cards
26
If two objects have the same mass but different volumes
the one with the larger volume has a lower density
New cards
27
If the density of water is 1 g/cm³, this means that a mass of 100 cm³ of water should be
100 grams
New cards
28
Density is a characteristic property of a substance. This means that the density of water
stays the same regardless of the volume
New cards
29
