How Do You Measure Thermal Conductivity and Dimensions of a Boiling Tube?

AI Thread Summary
The discussion revolves around measuring the thermal conductivity of a boiling tube, specifically querying whether it matches that of Pyrex glass. Participants emphasize the need for specific material details to provide accurate thermal conductivity estimates. For determining the radius of the boiling tube, it's suggested to use the internal diameter for precision. The thickness can be calculated by subtracting the internal diameter from the external diameter and dividing by two, although direct measurement with a micrometer is also recommended. Accurate measurements and material specifications are crucial for reliable results in thermal conductivity experiments.

Uhmm.. i faced some problem with my experiment of finding the thermal conductivity of glass..i hope that someone can help me.
May i know the extimation of the thermal conductivity of a boiling tube??
isit the same as the thermal conductivity of pyrex glass??
when i want to find the radius of the boiling tube, should i take the reading of the external diameter divided by 2 or the internal diameter divided by 2??
and about the thickness of the boiling tube, its the external diameter deduct the internal diameter then divided by 2 isit??:confused:
i will really appreciate your help..

Not unless you specify the material and the thickness.

I don't know since you don't say what it is.

Which one do you think?

Yes, it is. OR ... you could just measure the thickness with a micrometer.
 

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}...
