What really is a Pascal and a Joule? - Physics Forums
Jan 21, 2015 · The same with Joule's. Don't think of it as Kg*m^2/s^2, think about it as a force being applied over a distance. Joule is energy, and an external force does work on an object by an amount of ##W=F\cdot ds## where F is the force and ds is a small chunk of the path that it travels (a line is 1d).
What is a Joule Second? - Explained Easily! - Physics Forums
Jul 9, 2010 · A joule in mechanical work is 1 N of force applied on an object to move it a distance of 1 m. So a joule persecond is doing the above action in one second. Btw, a "joule per second" and a "joule second" are not the same thing. Jule per second is dividing by seconds, joule second would be multiplying by seconds.
How to convert cm^-1 into erg or joules - Physics Forums
Feb 5, 2010 · You cant, because cm^(-1) is not a unit of energy. The base units of energy are m l t^(-2). For example Ergs are grams cm seconds^(-2) and Joules are kg m seconds^(-2).
Why is Joule-Thomson effect isenthelpic? - Physics Forums
Aug 26, 2017 · Let's have an experimental apparatus for realization of Joule-Thomson effect. It could be a thermally isolated pipe with a porous board separating two compartments inside. Different pressures can be set in the second compartment. The gas flows through the pipe and we measure temperature and pressure on the outlet.
Entropy Change from Joule Expansion - Physics Forums
Aug 27, 2012 · Joule expansion is not reversible and there is a nonzero entropy change. Since the energy E of an ideal gas is given by E = 3/2 NkT, and since no heat or work is performed on the system, the temperature must be the same.
Joule Mobile Mass Transporter Project - Physics Forums
Dec 28, 2008 · The Joule Mobile Mass Transporter has a wide range of potential applications, including transporting materials for construction projects, moving goods in logistics and shipping industries, and even transporting large vehicles or machinery. What are the advantages of using the Joule Mobile Mass Transporter over traditional transportation methods?

Why 1 liter * atm = 101.33 joules - Physics Forums
Dec 14, 2016 · Are you asking why it comes out equal to 101.33 Joules, or why a pressure (atm) time a volume (liter) gives an energy (joules)?
