Linear and Volume expansion Problem

Click For Summary
SUMMARY

The discussion focuses on calculating volume expansion in a 2.00-liter aluminum cylinder filled with gasoline as both are heated from 5.00°C to 58.0°C. The relevant equation used is ΔV=V°βΔT, where the coefficients of volume expansion for gasoline (2.88e-3), aluminum (7.2e-5), ethyl alcohol (1.12e-4), mercury (1.82e-4), and glass (2.7e-5) are provided. The initial calculation for gasoline spillage was incorrectly performed without accounting for the expansion of the aluminum container. The correct understanding of volume expansion coefficients is crucial for accurate comparisons among substances.

PREREQUISITES
  • Understanding of volume expansion and the equation ΔV=V°βΔT
  • Familiarity with coefficients of volume expansion for various materials
  • Basic knowledge of thermal expansion concepts
  • Ability to perform unit conversions (e.g., liters to cubic centimeters)
NEXT STEPS
  • Research the application of volume expansion equations in real-world scenarios
  • Learn about the thermal properties of different materials and their coefficients of expansion
  • Explore the implications of thermal expansion in engineering and design
  • Study the effects of temperature changes on fluid dynamics in closed systems
USEFUL FOR

Students studying thermodynamics, engineers involved in material selection, and anyone interested in the practical applications of thermal expansion principles.

[a]Homework Statement

1.) A 2.00-liter aluminum cylinder at 5.00°C is filled to the brim with gasoline at the same temperature. If the aluminum and gasoline are warmed to 58.0°C, how much gasoline spills out? [Hint: Be sure to account for the expansion of the container. Also, ignore the possibility of evaporation, and assume the volume coefficients are good to three digits.

2.)Assuming all have the same initial volume, compare the following substances by the amount of volume expansion due to an increase in temperature: glass, mercury, aluminum, ethyl alcohol. (See the table below. Select all that apply.)
Ethyl alcohol would have the smallest expansion.
Ethyl alcohol would have the largest expansion.
Mercury would have the smallest expansion.
Mercury would have the largest expansion.
Glass would have the smallest expansion.
Glass would have the largest expansion.
Aluminum would have the largest expansion.
Aluminum would have the smallest expansion.

Relevant equations

ΔV=V°βΔT

Coefficient of Volume Expansion
Ethyl 1.12e-4
mercury 1.82e-4
glass 2.7e-5
aluminum 7.2e-5
gasoline 2.88e-3


[c] Attempt
For the first question, I do not know how to factor in the expansion of the container. This is what I did.
ΔV=(2L)(2.88e-3/°C)(53°C)= 0.30528 L= 305 cm3

I thought for the second question that aluminum would have the largest expansion and ethyl alcohol would have the smallest, but this was not correct.

Apply the same equation to the aluminum container.

The designation "e-4" after a number means ×10-4. Likewise for e-3 and e-5. So for example, 3e-2 is the same as 0.03. Does that help?
 
nevermind I figured it out. thanks
