Air temperature and relative humidity

AI Thread Summary
In sauna rooms, the air temperature can exceed 90° C (194° F) with low relative humidity around 10%, allowing for prolonged exposure without severe harm. The key difference lies in the heat transfer properties of air versus water; water conducts heat much more efficiently, leading to rapid burns. Additionally, the body's ability to cool itself through sweating in a sauna mitigates the risk of overheating. In contrast, immersion in hot water prevents effective cooling and increases the risk of burns. Thus, the environment in a sauna is fundamentally different from that of hot water, enabling safer exposure at the same temperature.

In sauna rooms, people spend time in conditions of air temperature over 90° C (194° F) with a relative humidity near 10%. However, if you stick your arm into liquid water that is at a temperature of 90° C (194° F), you will be severely burned in less than one minute. Give two reasons why people are able to spend time in a sauna, but are severely burned in water at the same temperature.

I have no idea why this is! Help?

Which has more heat? A sauna with a relative humidity of 10% or a bucket of water, both at the same temperature, 90 C?
 
You can cool yourself in a sauna by sweating. If you were wearing a coat in a sauna you would probably over heat and die.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

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}...
