Specific Heat Capacity: Comparing Spheres

Click For Summary

Discussion Overview

The discussion revolves around the concepts of specific heat capacity and heat capacity, particularly in relation to comparing two spheres. Participants explore the definitions and relationships between these concepts and consider how to experimentally determine the specific heat capacity of the materials involved.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants clarify that "specific heat capacity" is not a standalone term, emphasizing the distinction between "specific heat" as a property of matter and "heat capacity" as an attribute of an object dependent on mass.
  • One participant suggests that understanding the relationship between specific heat and heat capacity is crucial for addressing the original question about the spheres.
  • Another participant notes that the specific heat capacity is determined by the material of the sphere, as indicated in the accompanying image, but expresses suspicion that the question may involve more complexity.

Areas of Agreement / Disagreement

Participants generally agree on the distinction between specific heat and heat capacity, but there is uncertainty regarding the implications of this distinction for the original question about the spheres. Multiple views on how to approach the question remain present.

Contextual Notes

There are unresolved assumptions regarding the experimental methods to determine specific heat capacity and the specific conditions under which the comparison is made. The discussion also reflects differing interpretations of the terminology used.

How do I know which one of these two spheres have more specific heat capacity?

Hi fabrc. Can you explain what the photo is showing us?
 
First, I am afraid you are gluing the words of two different concepts...probably because they are directly related, but you need to keep in mind that they are two separate concepts.

To be sure, there is no "Specific Heat Capacity"; instead, you have two concepts:

"Specific Heat", this is a property of matter.

"Heat Capacity", this is an attribute on an object that depends on its "specific heat" and on its mass.

Once you understand these two concepts and how they relate to each other (go back to read the textbook or google...I got a few links right away), you should be able to explain what experiment you can do to answer the correct question.

I googled it, as you suggested. This is the first link: http://en.wikipedia.org/wiki/Heat_capacity

Taken from the second paragraph on that page: '. . . and the specific heat capacity, often simply called specific heat, is the heat capacity per unit mass of a material.'
 
If you take the question at face value... The specific heat capacity depends only on the material the sphere is made of and that's stated on the image.

However I suspect there is more to the question.
