Evangelista Torricelli discovered atmospheric pressure. Secretly, he created an expierement with some of his friends. By filling a bowl with Mercury and placing a six foot long glass tube upside down into it, a vacuum was created, causing the mercury to rise up. This was an early barometer. The reason this expierement was kept secret was probably because in 1643, this would have been considered witchcraft because a vacuum was considered impossible.

Who Discovered Isobars In Chemistry and Isobar Definition?
Isobars are a point or line drawn on map that connects the places of constant pressure e.g, atmospheric pressure or sea level.
What is Neptune's atmospheric pressure compared to earth's atmospheric pressure?
42% higher
Does Mars have extreme pressure?
The atmospheric pressure of Mars is 6 millibars as opposed to the 1,013 millibars of atmospheric pressure on Earth. Thus, its atmospheric pressure in relationship to Earth is extremely low.
What is the Significance of atmospheric pressure?
The atmospheric pressure plays a huge role when determining the weather. If the pressure is high, winds will be more active.
What atmospheric pressure causes hurricanes?
Hurricanes form from areas of low atmospheric pressure.
What is a sentence with the word atmospheric pressure?
Atmospheric pressure
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
rain occurs in low atmospheric pressure.
Who Discovered Isobars In Chemistry and Isobar Definition?
Isobars are a point or line drawn on map that connects the places of constant pressure e.g, atmospheric pressure or sea level.
How does the human body resist the atmospheric pressure?
because our body pressure is equal to the atmospheric pressure.
Can mean effective pressure less than atmospheric pressure?
no Because any body subject is affected by the atmospheric pressure in the case of its occurrence under the pressure of what it means that the pressure for increased atmospheric pressure.
What is the relation between pressure in atmosphere and pressure?
Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
What is Neptune's atmospheric pressure compared to earth's atmospheric pressure?
42% higher
How does the atmospheric pressure at altitudes sea level compare with atmospheric pressure at sea level?
the atmospheric pressure below sea level is highter (novanet)
Is gauge pressure is the sum of true pressure and atmospheric pressure?
No, it is the DIFFERENCE between the true and atmospheric pressures.
What does absolute pressure include that gauge pressure does not?
abosulute pressure includes the atmospheric pressure while gage pressure gives the pressure above atmospheric pressure
Does Mars have extreme pressure?
The atmospheric pressure of Mars is 6 millibars as opposed to the 1,013 millibars of atmospheric pressure on Earth. Thus, its atmospheric pressure in relationship to Earth is extremely low.
What is the Significance of atmospheric pressure?
