Why you use mercury manometer to measure atmospheric pressure at sea level rather alcohol?
Mercury has two advantages over alcohol when it comes to measuring pressure in a manometer: 1) it is far denser than alcohol. A column of mercury need only be about 760 mm ( about 3/4 of a meter) high to exert a pressure equal to atmospheric pressure at sea level. Alcohol would have to be over 13 meters high to reach the same pressure! (rather impractical) 2) Mercury has a very low vapor pressure so it doesn't evaporate when exposed to the atmosphere. It also contributes a negligible amount of pressure above the column on the sealed end of the manometer for pretty much any atmospheric temperature. Alcohol has a significant vapor pressure so it would tend to evaporate when exposed to the atmosphere. It also has a high enough vapor pressure that it would contribute a noticeable amount of pressure on the sealed end of the manometer - and the pressure would vary quite noticeably over the range of temperatures that atmospheric manometers are commonly exposed to - so the manometer reading would always have to be corrected for temperature - more so than the mercury manometer must be.
Natural fiber clothing is preferable laboratory attire because?
it will burn rather then melt.
What makes metals deform plastically rather than elastically?
Yes, excepting mercury.
Can you wear clothes on the planet mercury?
Yes, However clothing IS optional as they burn off rather quickly. The average temperature on Mercury is 456.84 degrees F Lots of popcicles are recommended.
What tests would you use to confirm you have a solution of Ag3PO4?
There is no such test to confirm you've a Ag3PO4-solution, because it is rather insoluble in water (about 0.00001 mol/L).
Can you give me a sentence that has the word preferable in it?
It is preferable to ride in a car rather than on a donkey.

Inclined-tube manometer why are they used to measure low pressure?
the fluid level in manometer will rise through an inclined line rather than vertical line. So when ever there is slight variation in pressure the manometer (inclined) will be able read it. The pressure drop is given by P=h*density*g*sin(angle).
How many babys showers can you give?
It is preferable to bath a baby, rather than shower it.
Natural fiber clothing is preferable laboratory attire because?
it will burn rather then melt.
How would you use preferable in a sentence?
Walking to the crosswalk would be preferable to getting hit by a car. It would be prefereable if you would pay in cash rather than check.
Why is it preferable to draw a line of best fit rather than to connect the dots?

Can you wash Spode dishes?
Yes. Washing "by hand" rather than placing in a dishwasher is preferable.
Is Mercury least conductive?
No. Mercury is actually rather conductive, being a metal.
Would you rather use alcohol or Mercury in a thermometer?
Alcohol. Mercury is very toxic.
Is mercury a moon of any planet?
No. Mercury orbits the sun, so it is a planet rather than a moon.
Why is it preferable to allow cold water to enter at the bottom of a condenser and exit at the top rather than vice versa?
