1.
The relative density (specific gravity) of a substance is defined as:
The ratio of the density of the substance to the density of pure water at 4°C
The product of density and the acceleration due to gravity
The mass of the substance divided by its volume at 100°C
The reciprocal of the buoyant force
2.
A metallic cube of side length 10 cm and density 7800 kg/m3 is completely submerged in water (density 1000 kg/m3). The buoyant force (upthrust) acting on the cube is (g = 10 m/s2):
10 N
68 N
100 N
78 N
3.
Pure water reaches its maximum density (1.000 g/cm3 or 1000 kg/m3) at a temperature of:
-4.0 °C
0.0 °C
4.0 °C
25.0 °C
