How do you find a PA in physics?
Section Summary
- Pressure is the force per unit perpendicular area over which the force is applied. In equation form, pressure is defined as. P=FA P = F A .
- The SI unit of pressure is pascal and 1 Pa=1 N/m2 1 Pa = 1 N/m 2 .
Which of the following is equivalent to pascal?
1 newton per square meter
Detailed Solution. The correct answer is option 1, i.e. 1 newton per square meter. The SI unit of pressure is Nm–2. A pascal is a pressure of one newton per square meter, or, in SI base units, one kilogram per meter per second squared.

What is Pam in chemistry?
Polyacrylamide ( IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH2CHCONH2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N’-methylenebisacrylamide.
What is PE in chemistry?
Explanation. In fact, it is possible to define pE, the negative logarithm of electron concentration (-log[e]) in a solution, which will be directly proportional to the redox potential. Sometimes pE is used as a unit of reduction potential instead of Eh, for example in environmental chemistry.
What is log P in chemistry?
Log P in Encyclopedia of Physical Organic Chemistry. The Log P value is the logarithm of its partition coefficient between n-octanol and water, is a well-established measurement of a compound’s hydrophilicity. Lipophilicity is a key factor for determining pharmacokinetic parameters such as permeation through a physical membrane,…
What is the Poh in chemistry?
pOH Definition: pOH is a measure of hydroxide ion (OH-) concentration. pOH is a measure of the alkalinity of a solution.
