- 5 kg/m³
- 500 kg/m³
- 0.5 kg/m³
- 0.05 kg/m³
- 50 kg/m³
The density of an object is 3.5 g/cm³. What is its specific gravity?
- 3.5
- 35
- 3.5 g/cm³
- 35 g/cm³
- Cannot be determined without the volume
Which of these statements about surface tension is TRUE?
- The water molecules are all attracted to each other (cohesion) and to the walls of the container (adhesion), such that there is a tension at equilibrium.
- The water molecules are all attracted to each other (adhesion) and to the walls of the container (cohesion), such that there is a tension at equilibrium.
- The water molecules are all repelled from each other (cohesion) and from the walls of the container (adhesion), such that there is a tension at equilibrium.
- The water molecules are all repelled from each other (adhesion) and from the walls of the container (cohesion), such that there is a tension at equilibrium.
- The water molecules feel no effect on each other, but the attraction to the walls of the container causes a tension at equilibrium.
A container filled with a fluid of unknown density weighs 3 times the same container filled with water. If the weight of the container by itself is negligible, what is the density of the fluid?
- 3 g/cm³
- 3 kg/m³
- 3000 g/cm³
- 0.3 kg/cm³
- This cannot be answered without knowing the volume
