1. Water has a high boiling point considering its low molecular weight.

This is because the O-H bonds are very polar and the H's are located at two corners of a tetrahedron giving water a high molecular polarity so that they tend to stick together.

2. Water forms hydrogen bonds between molecules

these bonds are rather flexible so that in liquid phase the molecules are relatively close together

but as the hexagonal arrangement of ice is formed the bonds are licked in place and as a result the average distance between molecules actually increases

with the result that ice is less dense than liquid water

Answer from: Quest

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.

Write 15 uses of a mercury barometer along with its characterestics
