AI Thread Summary
Steam at 100°C causes more severe burns than water at the same temperature due to its higher kinetic energy and the energy required for water to convert into steam, known as latent heat of vaporization. This process increases the energy transfer capability of steam, making it more effective at causing burns. Additionally, superheated steam has a lower specific volume, allowing for more efficient energy transfer and higher kinetic energy, which is beneficial in applications like boilers. The discussion confirms that steam's properties contribute to its greater burn severity compared to water. Understanding these differences is crucial for safety and handling in environments where both steam and water are present.

Which gives the more sever burn, water or steam both at 100°C? I think it is the steam because it has more kinetic energy in it, as the water molecules have broken the bonds of the liquid and has a lower specific heat capacity, but I would like some confirmation, or if incorrect the right answer and why.
Thanks in advance to the person/s who reply

Yes, steam at 100 degrees would cause the more severe burn owing to the fact that for water to be converted into heat, energy is required (known as latent heat of vapourisation), which in turn increases the KE of steam molecules .

hi,
specific volume of vapour at super-heated condition is less than at saturated vapour condition, hence, super-heated steam is easily transferable(higher KE), that is why, these are applied in boilers as they are carried at a faster rate & the energy carried by each vapour part is higher enough to cause turbine operation at a lower mass flow rate due to its high KE..

Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
