The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]
One, limited to chromium picolinate, a common supplement ingredient, reported a statistically significant −1.1 kg (2.4 lb) weight loss in trials longer than 12 weeks. [134] The other included all chromium compounds and reported a statistically significant −0.50 kg (1.1 lb) weight change. [ 135 ]

When atomic mass is shown, it is usually the weighted average of naturally occurring isotopes; but if no isotopes occur naturally in significant quantities, the mass of the most stable isotope usually appears, often in parentheses. [8] In the standard periodic table, the elements are listed in order of increasing atomic number.
Several small-scale studies (involving 15 or fewer test subjects) conducted in the 1950s and 1960s reported that adrenochrome triggered psychotic reactions such as thought disorder and derealization. [5]
Specific entropy may be expressed relative to a unit of mass, typically the kilogram (unit: J⋅kg −1 ⋅K −1). Alternatively, in chemistry, it is also referred to one mole of substance, in which case it is called the molar entropy with a unit of J⋅mol −1 ⋅K −1 .
The unified absolute pH scale is based on the absolute chemical potential of the proton, as defined by the Lewis acid–base theory. This scale is applicable to liquids, gases, and even solids. [23] The advantages of the unified absolute pH scale include consistency, accuracy, and applicability to a wide range of sample types.
