# Specific heat of solids discussion rubric

Einstein-Debye Specific Heats The Einstein-Debye phonon model produced agreement with the low-temperature cubic dependence of specific heat upon temperature. Then each prac report is printed out, de-identified, and placed face down around the room with the prac group number written clearly on the back. Or had I? Broad melting point range is an indication of the presence of impurities in the compound being analyzed. Solid Solid Copper The molar heat capacity does not decrease with temperature as rapidly as suggested by Einstein's model because these long wavelength modes are able to make a significant contribution to the heat capacity even at very low temperatures.

And instead of simply giving students the work sample, I also wanted to deconstruct it for them in a way that they could easily pull out the key points. I wanted to see if students like this whole process so I asked them about it. Note: Maybe it was just because my rubric sucked?

• SPECIFIC HEAT OF SOLIDS RUBRIC. Introduction: ______ (2) The problem is ______ (3) Discuss three possible sources of error. ______ (3) State how each. PRE-LAB DISCUSSION: The amount of heat required to raise the temperature of a solid body an intrinsic characteristic of the material forming the body called specific heat (cp).

## Debye Theory of Specific Heat

It will be graded according to the standards in the Lab Rubric. *The discussion should be the focus of the report where the results summarized in the data the heat capacity (Cvcal) of the calorimeter via.
Sound wave frequencies are far lower than the typical vibration frequencies of gaseous molecules. Nevertheless, both curves exhibit sharp cut-offs at high frequencies, and coincide at low frequencies. Thinking about the assessment of these reports in detail, I realised there were two levels at which I could give scaffolding and feedback, surface and deep structure.

Hi Ollie, this is a great post.

By doing this experiment, we can get a better understanding of the relationship between voltage and current, whilst also applying an Ohmic resistor in the circuit.

The purpose of the present investigation is to explore the impact of the voltages the discrete independent variable on the current the continuous dependent variable in the built circuit.

It produces good agreement with the transition to the Dulong and Petit limit at high temperatures.

Thus, it is likely and is, indeed, the case that lattice vibrations are not frozen out at room temperature, but, instead, make their full classical contribution to the molar specific heat of the solid. It is plausible that these modes are not particularly sensitive to the discrete nature of the solid: i.

From Reif. Interesting what you say about not using CJ for formative assessment.

Object: To determine the specific heat of a given solid specimen. Theory: Thermal energy is an internal energy that consists of the kinetic and potential energies. Page 6 - RUBRIC. This was The Specific Heat Capacities of Some Common Substances.

*The symbols (s), (0, and (9) indicate the solid, liquid, and gaseous states. Discuss the similarities and differences between a liquid.

specific heats of solids below 1°K. are of considerable value in increasing our .

### Specific heats of solids

as they apply to the metals discussed here* Some other types of. ().
Debye's Contribution to Specific Heat Theory Einstein's oscillator treatment of specific heat gave qualitative agreement with experiment and gave the correct high temperature limit the Law of Dulong and Petit.

How about impure substances and what is the observed melting point? The experiment aims to investigate the relationship between potential difference, current and resistance, and examine how different voltages applied affect the total current, on a series circuit.

The final step in explaining the low temperature specific heats of metals was the inclusion of the electron contribution to specific heat. All rights reserved. The detail really helps.

 She twerkin k camp clean up clip Bloody brilliant!All handy stuff. This is going to cause the melting point of A to be depressed or lowered when found in a mixture with another compound. Einstein-Debye Specific Heats The Einstein-Debye phonon model produced agreement with the low-temperature cubic dependence of specific heat upon temperature. Logging In Obtain the melting temperatures of each solid following the instructor's directions.
