Which pair of properties do all liquids have?
a) fixed volume; no definite shape
b) conducts electricity well; compressible
c) compressible; brittle
d) good conductor of heat; takes shape of container

The answer is A) Fixed volume and no definite shape

Explanation:

All the liquids has in common these characteristics:

1. Does not have a defined shape.

2.Fluency, ability to leave a container.

3. Viscosity, resistance to flow by internal forces of the substance.

4. Adherence, ability to "stick" to another substance.

5. Surface tension . Capacity to resist the penetration.

6. capillarity, depends on the surface tension and it is the ability to flow through and immersed pipe.

7. density, relation between mass and volumen. Its smaller than the solids.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the answer is a. at the equator
