Specific Heat: Its Influence on Temperature

Click For Summary

Discussion Overview

The discussion revolves around the concept of specific heat and its relationship with temperature. Participants explore whether specific heat varies with temperature and the implications of this variation in different states of matter. The conversation includes theoretical considerations and personal reflections on the topic.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant suggests that specific heat is expected to increase as the temperature of a substance rises, questioning the validity of this idea.
  • Another participant confirms that specific heat capacity does vary with temperature, noting that values tend to level off around room temperature and that there is often an exponential-like rise from very low temperatures.
  • A third participant posits that it may require more heat to raise the temperature of an object as it gets hotter, attributing this to the increased distance between atoms in a heated substance.
  • A fourth participant reiterates the definition of specific heat, emphasizing the amount of heat needed to raise the temperature of 1 kg of a substance by 1 degree Celsius, while indicating that their explanation does not involve volume considerations.

Areas of Agreement / Disagreement

Participants express varying views on the relationship between specific heat and temperature, with some agreeing on the variability of specific heat with temperature while others question the implications of this variability. The discussion remains unresolved regarding the exact nature of this relationship.

Contextual Notes

Some participants mention personal interpretations and uncertainties regarding scientific terminology, which may affect the clarity of their contributions. There are also references to specific heat in different states of matter, but these points are not fully explored.

Hello.
The other day i couldn't sleep, so i started to think.
After some long thinking, i reached a concludion (i was half sleep anyway !).
I reached the conclusion that the specific heat of any matter is supposed to raise as the temprature of the body raises.
So, am i kind of right ?
Thank you :smile:

Does specific heat capacity vary with temperature? Yes. The values usually start to level off once you reach room temperature (there's often an exponential-like rise from very cold temperatures until you reach room temperature for a wide variety of substances) which allows most processes of general interest (e.g. in chemistry & biology) to be treated with a constant specific heat capacity.
 
Specific heat is a measure of how much heat it takes to raise the temperature of something 1 degree Celsius.

I imagine it would be true that as the object reaches a higher temperature it would require more heat to raise it's temperature. This is probably due to the fact that the atoms are farther apart when the substance is hot. Generally speaking, solids have lower specific heat than liquids (ice is about half that of water).

I always had a problem with the scientifical english terms, but i remember that the specific heat is "the amount of heat energy needed to raise 1 kg of a certain matter 1 celsius degree.
Anyway, my explanation of this has nothing to do with volume (i will write it later after i see some replies).
