Can the Coefficient of Expansion Be Expressed in Both Kelvin and Celsius?

AI Thread Summary
The coefficient of thermal expansion can be expressed in both Kelvin and Celsius without the need for conversion, as a change of one degree in either unit represents the same temperature change. This is due to the fact that both scales have the same incremental value but differ in their starting points. Therefore, the coefficient of expansion for mercury remains consistent whether measured in Kelvin or Celsius. Understanding this relationship simplifies calculations in thermal expansion. The discussion clarifies that no unit conversion is necessary for accurate results.

I just have a quick question. In my assignment the coefficient of expansion for mercury is listed in K, and the temperatures given are listed in degress C.

Online I've seen the exact same coefficient of expansion (1.8 x 10-4) but in Celsius.

Can the coefficient be in either units, and therefore do I need to change the units of my temperature to get the correct answer?

No you don't need to convert between the two, one degree kelvin is of the same magnitude as one degree celcius. In otherwords if the temperature is increased by 1 degree celcius it is also increased by one degree kelvin.

thanks that makes sense
 
Kelvin and celsius a scales use the same divisions but different zero starting points thus the coefficient of expansion is exactly the same in either units as there is a 1:1 relationship.

Edit: Too late
 
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: 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...
