At first, I thought it was simple, but one commenter pointed out a very non-intuitive effect. I had to go do the experiment myself with...

SPOILER! The direction of motion depends on the both the angle of pull and the gear ratio:

Forward. I am poor at finding the puzzle here.

I will try. For 1kg liquid water at boiling temperature T under constant pressure p to become steam gas completely, we provide heat...

As far as I see in the web and AI answers they use Clapeyron Clasusius equation to explain it. I wonder if it is what expected by the...

It is a Fourier series which has abundant applications. it has relation with delta function. [EDIT] Though a bit different from your...

Q‘=Q+W > Q where W is work done to the water liquid-steam system in adiabatic compression process from Figure 3 to 4 where number is...

Good design. Say steam is ideal gas V=nRT/p Say n and T are fixed, V depends on p which depends on weight.

For a meaningful comparison, one needs a controlled process. What I have in mind is the thought experiment shown on the right. Start...

Area of observable universe is spreading just now. We may be able to find some scientific treasures in new area in future. That seems...

Volume of 1 kg steam of 100 oC with no dispersion in 100 oC atmosphere seems depend on pressure of atmosphere as variable forgetting...

I don't see the distinction between separation of variables, $$\Psi(\mathbf{r},t)=R(\mathbf{r})T(t)$$ with trigonometric function T...

Since latent heat is expressed in J/kg, I think we need to convert the amount into mass.

Fermi Dirac distribution of conduction electron gas in metal for T>0 suggests interaction of electrons including degenerate ones. Two...

Ideally all exhasted plasma has momentum of same direction backward. Exhasuted plasma would have the least mass and the maximum...
