Undergrad How to find composition using Specific HEat

Click For Summary
SUMMARY

The discussion focuses on solving an inverse problem to determine the composition of a mixture based on its specific heat capacity. Given a mixture with a specific heat of 780 J/kg·K, composed of copper (specific heat 400 J/kg·K) and iron (specific heat 890 J/kg·K), participants emphasize the necessity of modeling specific heat as a function of composition. The approach involves using the specific heats of the pure materials to derive the unknown proportions of each component in the mixture.

PREREQUISITES
  • Understanding of specific heat capacity and its units (J/kg·K)
  • Familiarity with inverse problems in thermodynamics
  • Basic knowledge of algebraic modeling techniques
  • Experience with material properties, specifically copper and iron
NEXT STEPS
  • Study the principles of inverse problems in thermodynamics
  • Learn about modeling specific heat as a function of composition
  • Explore numerical methods for solving algebraic equations
  • Investigate the specific heat capacities of various materials for comparison
USEFUL FOR

Students and professionals in materials science, thermodynamics researchers, and engineers involved in material composition analysis will benefit from this discussion.

IS it possible?
say if the specific heat is 800
and the composition is made up of 2 materials
one which has specific heat of 850
and the other of 750
 
Science news on Phys.org
Its an inverse problem.

You'd need to assume a model for the specific heat as a function of composition and the specific heats of the pure materials, and use the model equation to solve for the unknown compositions.
 
hmmm

say if it was made out of copper n iron
copper having 400 specific heat heat capacity
Iron having 890 specific heat
and the mixture had 780 specific heat capacity
^ assume the values are that
can u show me how to do the inverse problem to find the composition?
 
no one is going to show you how to do anything.

you need to figure it out on your own.
