Pressure groups are also known as interest groups, which is a structural grouping that seeks to influence government policy or government actions. They differ from a political party because they do not seek to win government but to influence those who win government. They are usually more narrow than a political party and generally single issue politics. The first pressure abolition society 1787 to appose slave trade.

In other words, a pressure group is an organization that tries to advance specific causes, issues, or interests.

What is the atmospheric pressure gauge pressure and absolute pressure and relation between them?

Atmospheric pressure is the pressure exerted by the weight of air in the atmosphere, typically measured at sea level and approximately equal to 101.3 kPa (kilopascals) or 1 atm. Gauge pressure is the pressure measured relative to atmospheric pressure, meaning it excludes atmospheric pressure from its measurement; it can be positive or negative depending on whether the pressure is above or below atmospheric pressure. Absolute pressure, on the other hand, is the total pressure measured relative to a perfect vacuum, and is calculated by adding atmospheric pressure to gauge pressure. The relationship can be expressed as: Absolute Pressure = Gauge Pressure + Atmospheric Pressure.


Gauge pressure and absolute pressure?

Gauge pressure is what you get when you take the reading from your tire pressure gauge. Absolute pressure is the pressure inside your tires plus the atmospheric pressure, which is roughly; 14.7 psi, 101.3 kPa (kilo-Pascals), or one atmosphere. Absolute pressure measures all of the pressure on your tires, inside and out, whereas gauge simply measures the pressure inside the tire.


What are the names given to 'pressure X' and 'pressure Y'?

In the context of thermodynamics or fluid mechanics, 'pressure X' is often referred to as "absolute pressure," which measures pressure relative to a perfect vacuum. Conversely, 'pressure Y' is commonly known as "gauge pressure," which measures pressure relative to atmospheric pressure. These terms help differentiate between different reference points when measuring pressure in various applications.


What is absolute pressure?

Absolute pressure is simply the addition of the observed gage pressure plus the value of the local atmospheric pressure.
