    Expansion Kelvin
AI Thread Summary
The discussion centers on calculating the volume of gasoline that spills from a steel gas tank as the temperature increases from 11.5 °C to 37.6 °C. The relevant equation for volumetric expansion is provided, using the coefficient of volumetric expansion for gasoline. A participant expresses confusion over whether to use Celsius or Kelvin for temperature changes, but it is clarified that the temperature difference remains the same in either scale. Additionally, the impact of the steel tank's volume change due to temperature is highlighted as a factor that needs consideration. Understanding both the gasoline and tank expansion is crucial for an accurate calculation.

Volumetric expansion Kelvin required?

Homework Statement



Suppose that the steel gas tank in your car is completely filled when the temperature is 11.5 °C. How many gallons will spill out of the 20.9- gallon tank when the temperature rises to 37.6 °C?

Homework Equations



βgasoline = 950 x10-6
ΔV = β(V0)ΔT

The Attempt at a Solution



ok so this rele seemed like a plug and jug question to me and i just can't figure out where i went wrong. This is what I did, my only questions are where did i go wrong or maybe are the temperatures supposed to be in Kelvins or would Celsius work to?

(950*10^-6)*(20.9)*(26.1)
why isn't this right?

Thanks yall

Since the size of a degree K and a degree C are the same, ΔT will be the same regardless of scale used.

Did you figure in the change in volume of the steel tank? Both are going to change (by different amounts) when the temperature changed.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
