Heat Capacity Calculations
The heat capacity formula comes in various forms, but they all amount to the same basic equation:
Q = mCΔT
This equation simply states that the change in heat Q of a closed system (a liquid, gas or solid material) is equal to the mass m of the sample times the temperature change ΔT times a parameter C called specific heat capacity, or just specific heat. The higher the value of C, the more heat a system can absorb while maintaining the same temperature increase.
Methodology
Calculation of heat capacity can be performed by various methods, including experimental measurements and first-principles calculations. Experimental measurements involve heating the sample and measuring the heat absorbed or released, as well as the resulting temperature change. While experimental methods are highly accurate, they can be time-consuming and expensive.
Services Items
- We use state-of-the-art computational techniques to perform first-principles calculations of heat capacities for a wide range of materials, including solids, liquids, gases, and complex mixtures. Our calculations are based on using quantum mechanical theory to solve the Schrödinger equation for the system. The heat capacity is then calculated based on the vibrational motion of the atoms or molecules in the material.
- We use DFT methods to accurately capture the electronic structure and vibrational properties of materials.
- Molecular dynamics simulations: Molecular dynamics simulations are used to study the behavior of atoms and molecules over time. We use molecular dynamics simulations to predict the thermodynamic properties of materials under different temperatures, pressures, and other conditions.
Deliverables
- Heat capacity data: We provide detailed heat capacity data for a wide range of materials, including solid crystals, polymers, liquids, gases, and complex mixtures. Our data includes heat capacity, entropy, enthalpy, and other thermodynamic properties as a function of temperature.
- Reporting and Analysis: Our team provides detailed reporting and analysis of computational results, including visualization of vibrational modes, comparison with experimental data, and insight into the underlying physical mechanisms that control heat capacity.
