The downward pressure on the hg in barometer is <u>the same as</u> the pressure of the atmosphere.
The atmospheric pressure or barometric pressure is the force exerted by the air in the atmosphere on the earth's surface.
The atmospheric pressure is caused by air molecules colliding with the surface. The atmospheric pressure at sea level is about 101 kPa and at the cruising altitude of a passenger plane it is 27 kPa.
The atmospheric pressure decrease as the height of a surface above ground level increases.
<h3>What is a barometer?</h3>
A barometer is a measuring instrument used to measure the atmospheric pressure or weight of the air, which is useful for making weather predictions.

2-methyl-propane or iso-propane
Answer:
The correct answer is: d-orbital
Explanation:
The transition metals are the chemical elements that belong to the B-group of the periodic table, from group 1B to 8B. The B-group is located between the groups IIA and IIIA in the periodic table.
The general electronic configuration of the chemical elements belonging to this group is (n-1) d¹⁻¹⁰ ns⁰⁻², because of the <u>partially filled d-subshell</u> in the ground state or excited state. <u>Therefore, the transition metals are refereed as the </u><u>d-block elements</u><u>.</u>
