An experiment at Sandia National Labs in New Mexico is performed at an atmospheric pressure of
788.7 millimeters of mercury (mm Hg). What is this pressure in atmospheres (atm)?

1.0  atm

Explanation:

Millimetre mercury:

It is the monometric unit of pressure. It is define as "The pressure exerted by the column pf mercury at the height of 1 millimetre.

It is represented as mmHg.

It can also be written as mm Hg.

Atmosphere (atm):

It is barometric pressure, define as "The force exerted by atmospheric column on per unit area".

It is written as "atm".

Conversion of  mmHg to atm:

788.7 mmHg × 1 atm/ 760 mmHg

1.0  atm

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
