Conversion from Gram per liter to Hector gram per liter

Basically, unit conversion means expressing the same property as a different unit of measurement

Explanation:

GRAM/LITER TO HECTOGRAM/MILLILITER (g/l TO hg/ml) FORMULA

To convert between Gram/liter and Hectogram/milliliter you have to do the following:

Step one :

First divide 0.001/0.001 / 0.1/0.000001 = 0.00001

Step two:

Then multiply the amount of Gram/liter you want to convert to Hectogram/milliliter.

= 0.00001* 4.2

= 0.000 042 hectogram/milliliter

GRAM/LITER TO HECTOGRAM/MILLILITER (g/l TO hg/ml) CHART

1 gram/liter in hectogram/milliliter = 0.00001 g/l

10 gram/liter in hectogram/milliliter = 0.0001 g/l

50 gram/liter in hectogram/milliliter = 0.0005 g/l

100 gram/liter in hectogram/milliliter = 0.001 g/l

250 gram/liter in hectogram/milliliter = 0.0025 g/l

500 gram/liter in hectogram/milliliter = 0.005 g/l

1,000 gram/liter in hectogram/milliliter = 0.01 g/l

10,000 gram/liter in hectogram/milliliter = 0.1 g/l

Answer from: Quest

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.

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

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
