Homework Help Overview

The discussion revolves around the concept of specific heat and its implications for temperature changes in different materials when subjected to the same amount of heat. Participants are exploring how specific heat values influence temperature rise in materials A, B, and C.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the definition of specific heat and its relevance to the problem. There are attempts to clarify how specific heat affects temperature change, with some questioning the implications of different specific heat values on temperature rise.

Discussion Status

The discussion is active, with participants providing definitions and interpretations of specific heat. Some guidance has been offered regarding the relationship between specific heat and temperature change, although multiple interpretations of the implications are being explored.

Contextual Notes

There is a request for definitions and clarifications, indicating that some participants may not have a complete understanding of specific heat. The original poster's question assumes a basic knowledge of the concept, which may not be uniformly shared among all participants.

Suppose I have the following materials with specific heat values as given:

Material A 5500J/kg.K

Material B 3900J/kg.K

Material C 9000J/kg.K

If I supply the same amount of heat to each which one will have the largest temperature rise?

More importantly why?

Can you give me a definition of specific heat? Look it up in your book, if necessary.

Q=mc(deltaT)

Q=Energy, c=specific heat m=mass delta T is change of temperature

Specfic heat is #J/kg.K where Kelvin is the Temp and J is joules.

The specific heat of a material is the amount of heat required to raise 1 Kg sample of the material, one Kelvin.

That sentence is all you need to answer the question.

So Material B because it has the lowest specific heat rating and won't require as much heat as the others?
 
Yes, therefore you use materials with high specific heat in cooling systems...
 
Okey Dokes - Thanks Nomy and Chroot - I appreciate your help.
