- What really is a Pascal and a Joule? - Physics Forums
Hi forum, First time poster I'm in thermo this year and it's the first time working with pascals and joules My teacher and most post just jump right into the equations, 1Pa = 1N m^2 and 1J = 1N * M But what really is a pascal? I get what a N is, force to move 1kg*m s^2 If I convert N, I get
- What is a Joule Second? - Explained Easily! - Physics Forums
I can easily picture joules per second (I just see light of varying intensities passing a point at varying rates) I don't know what a joule second is I know that Plancks constant is just to use the frequency of the photon to find out its energy but what in the name of God is a joule second?
- Torque Joules: Fact or Fiction? - Physics Forums
Wikipedia says that the unit of magnetic dipole moments is calculated by Joule B that means that the torque is measured by joules I really doubt that, it seems non sense
- How to convert cm^-1 into erg or joules • Physics Forums
I'm not sure if this is the right place for this, but I can't seem to find how to convert cm^-1 into erg or joules It's a pretty dumb question, but I can't find the answer anywhere Thanks a lot in advance!
- Joules per Coulomb and the Volt - Physics Forums
Then 1 volt means 1 joule per coulomb; 2 volts mean 2 joules per coulomb, and 5 volts mean 5 joules per coulomb But what is meant by 2 or 5 volts? If one coulomb contains a set amount of electrons, how can one coulomb have more energy or potential to do work than another coulomb? What is different?
- Converting Coulombs to Joules Without Voltage - Physics Forums
Converting coulombs to joules requires knowledge of voltage, as they are fundamentally different quantities The relationship between them involves current and power, where joules are calculated using the formula Joule = Volt * Coulomb The discussion highlights the confusion surrounding the original question, emphasizing that without voltage, the conversion is not feasible Participants also
- What is the Definition of 1 Joule and How Does it Relate to Lifting . . .
Someone told me that 1 Joule is roughly the amount of energy required to lift a 1 kilo object 10 cm of the ground This sounds weird to me Seems the amount of energy required would depend on how fast you lifted the object? The more time you were to spend lifting, the more energy you would spend
- Free expansion of a real gas vs Joule-Thomson effect
The discussion explores the differences between the free expansion of real gases and the Joule-Thomson (J-T) effect It clarifies that while free expansion of an ideal gas results in no temperature change due to constant internal energy, real gases experience temperature changes due to intermolecular forces
