Noble Gases

The elements in group 18 are noble gases (helium, neon, argon, krypton, xenon, and radon). They earned the name “noble” because they were assumed to be nonreactive since they have filled valence shells. In 1962, Dr. Neil Bartlett at the University of British Columbia proved this assumption to be false. These elements are present in the atmosphere in small amounts. Some natural gas contains 1–2% helium by mass. Helium is isolated from natural gas by liquefying the condensable components,...

Molecular Comparison of Gases, Liquids, and Solids

Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the $2,000...

Perfect Gases and the First Law

A perfect gas obeys the equation of state pV = nRT. The internal energy of a perfect gas remains unaffected by volume alterations. Therefore, the internal energy of a perfect gas is solely dependent on temperature.Consider an ideal gas enclosed in a cylinder situated within a substantial constant-temperature bath. In an isothermal process, where the temperature remains constant, the change in internal energy equates to zero. Thus, according to the first law of thermodynamics, heat absorbed (q)...

Adjusting Entries

2025
In accounting, a business's economic activities are segmented into designated time intervals, typically monthly, quarterly, or annually, known as accounting periods. This segmentation facilitates consistent tracking, summarization, and reporting of financial data, enabling stakeholders to accurately evaluate a company's performance and financial position. Companies must incorporate adjusting entries at the close of each period to ensure that financial reports conform to the accrual basis of...
FAQs
Valves, orifices, regulators, and mass flow controllers change gas delivery by altering the resistance or pressure conditions in a flow path. That change influences how much gas passes, the pressure maintained, or the direction it takes. Selecting among these components lets an engineer match control behavior to equipment needs, whether the system requires regulated pressure, metered flow, or directional control.
Sensors provide the measurement needed to detect whether actual operation differs from a desired setpoint. In a feedback system, the measured condition is compared with that target, and the control arrangement corrects the deviation. This continuous adjustment helps maintain process stability when gas delivery changes, rather than relying only on a fixed initial setting.
A pressure difference across a component provides part of the driving condition for gas movement, while resistance determines how strongly the component restricts delivery. Adjusting either factor changes the resulting flow behavior. Engineers therefore consider both together when seeking stable supply, avoiding excessive pressure, or preventing inadequate delivery.
Poor adjustment can leave a system with excessive pressure, leaks, or an inadequate gas supply. Those conditions undermine safe operation and can destabilize a process. Correcting the resistance or pressure conditions, then using sensing and feedback when available, helps keep delivery closer to its intended operating point.
An engineering workflow begins by identifying whether the system must control flow rate, pressure, or direction. The engineer then adjusts a suitable component, such as a valve, orifice, regulator, or mass flow controller, and checks the resulting condition against the target. Where available, sensors and feedback provide ongoing correction.
It supports combustion, pneumatic actuation, ventilation, chemical processing, and laboratory gas delivery. In these settings, the purpose of adjustment differs with the process, but accurate control can improve stability, energy use, and product consistency. It also helps limit excessive pressure, leaks, and insufficient supply, linking flow control directly to operational safety.
