Specific Heat Capacity and Thermal Conductivity

Click For Summary
SUMMARY

The discussion centers on the relationship between specific heat capacity and thermal conductivity in determining the final temperature of objects placed in a hot oven. The key conclusion is that regardless of the specific heat capacity and thermal conductivity values, all objects will reach the same temperature upon removal from the oven, provided they are allowed to achieve thermal equilibrium. The relevant equations discussed include Q=mcΔT for specific heat capacity and Q/Δt=k(A/L)ΔT for thermal conductivity.

PREREQUISITES
  • Understanding of specific heat capacity and its equation Q=mcΔT
  • Familiarity with thermal conductivity and its equation Q/Δt=k(A/L)ΔT
  • Basic knowledge of thermal equilibrium concepts
  • Ability to analyze and compare physical properties of materials
NEXT STEPS
  • Research the concept of thermal equilibrium in thermodynamics
  • Explore the implications of specific heat capacity in material selection for thermal applications
  • Study the effects of thermal conductivity on heat transfer in different materials
  • Investigate practical applications of specific heat capacity and thermal conductivity in engineering
USEFUL FOR

Students studying thermodynamics, physics educators, and professionals in materials science or engineering who need to understand heat transfer principles.

Homework Statement



To summarize, I am given 6 objects and their corresponding specific heat capacity and thermal conductivity values. All objects have the same mass. The question is asking me to rank the objects based on temperature if they are put in a hot oven until they reach thermal equilibrium and removed.

Homework Equations



Q=mc\DeltaT (specific heat capacity)
Q/\Deltat=k(A/L)\DeltaT (thermal conductivity)

The Attempt at a Solution



I initially ranked the objects from lowest heat capacity to highest heat capacity because I was thinking that the objects that require less energy to raise their temperature will be hottest upon removal.
I'm not really sure how to relate thermal conductivity and specific heat capacity to find out their temperatures after removal... My textbook doesn't help either.

...Nevermind. I realized that it doesn't matter what the values for specific heat capacity and thermal conductivity... if the oven is maintained at the given temperature, all objects will be the same upon removal if they are allowed to reach thermal equilibrium.
