It is usually expressed as calories per degree in terms of the actual amount of material being considered, most commonly a mole (the molecular weight in grams). The heat capacity in calories per gram is called specific heat. The definition of the calorie is based on the specific heat of water, defined as one calorie per degree Celsius. At sufficiently high temperatures, the heat capacity per atom tends to be the same for all elements. For metals of higher atomic weight, this approximation is already a good one at room temperature, giving rise to the law of Dulong and Petit.</p> <p>Temperature (degrees Celsius), Isobaric specific heat (joules per kelvin per mole), Isobaric specific heat (kilojoules per kelvin per kilogram), Isobaric specific heat (kilowatts-hour per kelvin per kilogram), Isobaric specific heat (kilocalories per kelvin per kilogram)</p> <p>0.01&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 76.026&nbsp;&nbsp; 4.2199&nbsp;&nbsp; 0.001172&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0079</p> <p>10&nbsp;&nbsp; 75.586&nbsp;&nbsp; 4.1955&nbsp;&nbsp; 0.001165&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0021</p> <p>20&nbsp;&nbsp; 75.386&nbsp;&nbsp; 4.1844&nbsp;&nbsp; 0.001162&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.9994</p> <p>25&nbsp;&nbsp; 75.336&nbsp;&nbsp; 4.1816&nbsp;&nbsp; 0.001162&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.9988</p> <p>30&nbsp;&nbsp; 75.309&nbsp;&nbsp; 4.1801&nbsp;&nbsp; 0.001161&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.9984</p> <p>40&nbsp;&nbsp; 75.300&nbsp;&nbsp; 4.1796&nbsp;&nbsp; 0.001161&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.9983</p> <p>50&nbsp;&nbsp; 75.334&nbsp;&nbsp; 4.1815&nbsp;&nbsp; 0.001162&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.9987</p> <p>60&nbsp;&nbsp; 75.399&nbsp;&nbsp; 4.1851&nbsp;&nbsp; 0.001163&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0.9996</p> <p>70&nbsp;&nbsp; 75.491&nbsp;&nbsp; 4.1902&nbsp;&nbsp; 0.001164&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0008</p> <p>80&nbsp;&nbsp; 75.611&nbsp;&nbsp; 4.1969&nbsp;&nbsp; 0.001166&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0024</p> <p>90&nbsp;&nbsp; 75.763&nbsp;&nbsp; 4.2053&nbsp;&nbsp; 0.001168&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0044</p> <p>100 75.950&nbsp;&nbsp; 4.2157&nbsp;&nbsp; 0.001171&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0069</p> <p>110 76.177&nbsp;&nbsp; 4.2283&nbsp;&nbsp; 0.001175&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0099</p> <p>120 76.451&nbsp;&nbsp; 4.2435&nbsp;&nbsp; 0.001179&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0135</p> <p>140 77.155&nbsp;&nbsp; 4.2826&nbsp;&nbsp; 0.001190&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0229</p> <p>160 78.107&nbsp;&nbsp; 4.3354&nbsp;&nbsp; 0.001204&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0355</p> <p>180 79.360&nbsp;&nbsp; 4.4050&nbsp;&nbsp; 0.001224&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0521</p> <p>200 80.996&nbsp;&nbsp; 4.4958&nbsp;&nbsp; 0.001249&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.0738</p> <p>220 83.137&nbsp;&nbsp; 4.6146&nbsp;&nbsp; 0.001282&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.1022</p> <p>240 85.971&nbsp;&nbsp; 4.7719&nbsp;&nbsp; 0.001326&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.1397</p> <p>260 89.821&nbsp;&nbsp; 4.9856&nbsp;&nbsp; 0.001385&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.1908</p> <p>280 95.285&nbsp;&nbsp; 5.2889&nbsp;&nbsp; 0.001469&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.2632</p> <p>300 103.60&nbsp;&nbsp; 5.7504&nbsp;&nbsp; 0.001597&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.3735</p> <p>320 117.78&nbsp;&nbsp; 6.5373&nbsp;&nbsp; 0.001816&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.5614</p> <p>340 147.88&nbsp;&nbsp; 8.2080&nbsp;&nbsp; 0.002280&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.9604</p> <p>360 270.31&nbsp;&nbsp; 15.004&nbsp;&nbsp; 0.004168&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.5836</p> <p>Contributor: Junjie Chen, ORCID: 0000-0001-5055-4309, E-mail address: komcjj@gmail.com, Department of Energy and Power Engineering, School of Mechanical and Power Engineering, Henan Polytechnic University, 2000 Century Avenue, Jiaozuo, Henan, 454000, P.R.
