Table of specific heat capacity values?

Click For Summary

Homework Help Overview

The discussion revolves around specific heat capacity, including the search for tables of specific heat values and clarification on units of measurement. Participants express confusion regarding the relationship between temperature measurements in Kelvin and degrees Celsius.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants share resources for specific heat capacity tables and inquire about the appropriate units for measurement. There is a discussion about the consistency of results when using different temperature units, and one participant raises a concern about discrepancies in their calculations.

Discussion Status

Some participants have provided links to resources, and there is an acknowledgment of the equivalence of temperature changes in Celsius and Kelvin. A participant has recognized a mistake in their calculations, leading to a clearer understanding of the topic.

Contextual Notes

There is mention of varying results based on the temperature unit used, and participants are exploring the implications of these differences on their calculations. The original poster's request for help indicates a need for foundational understanding of specific heat capacity.

Hey ya. I need some help with specific heat capacity. :cry: Does anyone know where i can find a table of specific heat capacity values? :redface: Also what are the units of specific heat capacity? do you have to measure the temperature in kelvin or degrees? Plz help, o:) Thanx

excellent, thanks a lot. will have a read through them.

A table of specific heat values can usually be found in the appendix of a chemistry textbook.

Or, click http://www.standnes.no/chemix/periodictable/specific-heat-capacity.gif

:redface: Also what are the units of specific heat capacity? do you have to measure the temperature in kelvin or degrees? Plz help, o:) Thanx

The SI units of specific heat are
[tex]\frac{\text{J}}{\text{kg} \cdot \text{K}}[/tex]
(In SI we use Kelvin :wink:)

I had a look at the sites, and one the table it said J/kg/oC
or J/kg/K. Does that meant then that as long as you keep to the same unit, you should get the same answer?
 
I have just worked out my specific heat capacities using both kelvin and oC and i got different answers. I got 954 J/kg/oC and 3968 J/Kg/K. When looking at the tables aluminium (which i think the metal is) has a specific heat capacity of around 900 J/Kg/K, but my kelvin answer is not near that! any suggestions on what i may be doing wrong?
 
How have you worked them out? Perhaps you could show an example calculation? If you are looking at change in temperature remember that the size of 1 oC is the same as 1K.

Thanx hootenanny. Of course, the change in temperature is the same in both oC and kelvin. Excellent! I was working out the change in temperature and then adding on 273 for kelvin! woops! YAY. Thank you sooooo much. I'm not confused any moure!
