What is an ordered arrangement of particles extends over a long distance in a solid, the material is called?

Crystalline

Explanation:

A crystalline solid  consist of atoms , molecules and ions that possess a definite repetitive pattern.The crystal structure depict the microscopic arrangement of atom inside it. The constituent(molecules, ions and atoms) that makes up the crystals are well ordered  forming a crystal lattice in all direction.

The pattern of formation of the crystals are repetitive. The process of formation of this crystal structure is known as crystallization. Not all solid are crystal  form example glass and ice.  This orderly arrangement of the particles in the solid usually exist through out the solid.  This solid are characterize by long range order with a small repeat unit . The pattern of array is called the crystal lattice. Example of crystalline solid is salt.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
