10. Find the mass density of a ball with 22.0 g and a radius of 0.875 cm.
Ede4ka [16]

Answer:

Mass (m) = 22.0 g

Radius (r) = 0.875 cm

Density (d) = ?

First find ( volume) ;

v =  \frac{4}{3} \pi \:  {r}^{3}  \\  \\ v =  \frac{4}{3}  \times 3.14 \times ( {0.875)}^{3}  \\  \\ v =  \frac{4}{3}   \times 3.14 \times 0.66992187  \:  {cm}^{3} \\  \\ v = 2.8 \:  {cm}^{3}

Density =  \frac{mass}{volume}  \\  \\ d =  \frac{m}{v}  \\  \\ d =  \frac{22}{2.8}  \\  \\ d = 7.857 \:  \frac{g}{ {cm}^{3} }

I hope I helped you^_^

What are properties of a liquid?
Oksi-84 [34.3K]

Answer:

Pressure

Surface

Flow

Fluency

Explanation:

*Surface

The surface tension is the force with which the surface molecules of a liquid are attracted to bring them inside and thus decrease the surface area.

*Flow

It is defined as resistance to flow. The viscosity of a liquid depends on the intermolecular forces:

-The higher the intermolecular forces of a liquid, its molecules have a greater difficulty moving between them, therefore the substance is more viscous.

-Liquids that are made up of long, flexible molecules that can bend and tangle with each other are more viscous.

* Pressure

if the molecules of the liquid have a greater intensity of intermolecular force, then they will be trapped in the liquid and will have less facility to pass into the gas phase.

    on the contrary to lower intensity of intermolecular force, then the molecules can escape more easily to the gaseous state.

*Fluency

This property allows liquids to easily pass through a hole regardless of size, as long as this hole is at a lower or the same level of the container where the liquid is stored.

This property indicates the deformability of a liquid which is very wide without requiring mechanical stress.
