ظرفیت گرمایی عناصر (صفحه اطلاعات)

• All values refer to 25 °C and to the thermodynamically stable standard state at that temperature unless noted.
• Values from CRC refer to "100 kPa (1 bar or 0.987 standard atmospheres)". Lange indirectly defines the values to be at a standard state pressure of "1 atm (101325 Pa)", although citing the same NBS and JANAF sources among others. It is assumed this inexactly refers to "ambient pressure".
