The SI unit of pressure is thepascal (Pa), with 1 Pa = 1 N/m2, where N is the newton, a unit of force defined as 1 kg m/s2. One pascal is a small pressure; in many cases, it is more convenient to use units of kilopascal (1 kPa = 1000 Pa) orbar(1 bar = 100,000 Pa)...

A new observation in surface chemistry: the variation of liquid–solid–gas contact angle with change in gas pressureSurface chemistryLiquid–solid–gasPMMATeflon FEPThe contact angles of water and of diiodomethane (DIM) on Teflon LFEP and on polymethylmethacrylate (PMMA), and also on a ...
This lab's goal is to investigate pressure and volume. Pressure is a continuous physical force exerted on or against an object by something in contact with it. But in physics and chemistry, gas pressure has a more specific definition. It is the pressure that gas molecules exert on the walls...
During the seventeenth and especially eighteenth centuries, driven both by a desire to understand nature and a quest to make balloons in which they could fly (Figure 1), a number of scientists established the relationships between the macroscopic physical properties of gases, that...

To solve the problem of determining the pressure required to compress a gas to three-fourths of its original volume, we can use Boyle's Law. Here's a step-by-step solution:Step 1: Understand Boyle's Law Boyle's Law states that
The gas constant is the physical constant in the equation for theIdeal Gas Law: PV = nRT P ispressure, V isvolume, n is the number ofmoles, and T istemperature. Rearranging the equation, you can solve for R: R = PV/nT The gas constant is also found inthe Nernst equationrelating the...
