Vaporization and Energy absorption

AI Thread Summary
In modern nanotechnologies, metals can be vaporized to create a thin, hard protective layer on surfaces. The discussion centers on calculating the energy required to heat 0.55 kg of iron from 1400°C to vapor at 2050°C. The final energy calculation yields 3,766,950 J. Participants confirm this result, indicating agreement on the calculation. This energy requirement is crucial for applications in nanotechnology.

In modern nanotechnologies, metals can be vapourized to coat onto the surface of another

material as a thin but hard protective layer. How much energy would it take to heat 0.55

kg of iron from 1400oC to vapour at 2050oC?

HEY ZOEY,

Did you get 3 766 950 J as a final answer?
 
HEY FIZZIX,
i did as a matter of fact, thanks for confirming good sir.
 

Thread 'The Effect of Linear and Rotational Motion on Measured Weight'

Consider an extremely long and perfectly calibrated scale. A car with a mass of 1000 kg is placed on it, and the scale registers this weight accurately. Now, suppose the car begins to move, reaching very high speeds. Neglecting air resistance and rolling friction, if the car attains, for example, a velocity of 500 km/h, will the scale still indicate a weight corresponding to 1000 kg, or will the measured value decrease as a result of the motion? In a second scenario, imagine a person with a...

Thread 'Coulomb gauge implies instantaneous radial electric field?'

Scalar and vector potentials in Coulomb gauge Assume Coulomb gauge so that $$\nabla \cdot \mathbf{A}=0.\tag{1}$$ The scalar potential ##\phi## is described by Poisson's equation $$\nabla^2 \phi = -\frac{\rho}{\varepsilon_0}\tag{2}$$ which has the instantaneous general solution given by $$\phi(\mathbf{r},t)=\frac{1}{4\pi\varepsilon_0}\int \frac{\rho(\mathbf{r}',t)}{|\mathbf{r}-\mathbf{r}'|}d^3r'.\tag{3}$$ In Coulomb gauge the vector potential ##\mathbf{A}## is given by...

Thread 'Simple thought experiment with Stefan-Boltzmann law: energy'

Dear all, in an encounter of an infamous claim by Gerlich and Tscheuschner that the Greenhouse effect is inconsistent with the 2nd law of thermodynamics I came to a simple thought experiment which I wanted to share with you to check my understanding and brush up my knowledge. The thought experiment I tried to calculate through is as follows. I have a sphere (1) with radius ##r##, acting like a black body at a temperature of exactly ##T_1 = 500 K##. With Stefan-Boltzmann you can calculate...
