1. Absolute configuration
The three-dimensional arrangement of the atoms around the chiral center of a molecule.

2. Absolute filter
A fine-pored, steam-sterilizable filter that is used to trap airborne microorganisms. The filter's pores are about 2 micrometers in diameter, smaller than the particles it is designed to remove.

3. Absolute gravity
In chemistry, the value that denotes the density (specific gravity) at standard conditions (for gases, these conditions are standard atmospheric pressure at 0 C).

4. Absolute risk
The excess risk due to exposure to a specific hazard (disease, injury, etc.)

5. Absolute time
One of the two types of geologic time ( relative time being the other), with a definite age date established mostly by the decay of radioactive elements, although ages may also be obtained by counting tree rings, decay of a specific type of atom, or annual sedimentary layers (such as varves in lakes or layers in a glacier). The term is in some disfavor because it suggests an exactness that may not be possible to obtain.

6. Absolute zero
This is the lowest possible temperature (0 Kelvin, -273.15 Celsius, -459.67 Fahrenheit). At this temperature, all molecular motion stops.

7. Absorption
The process of absorbing; specifically: * In physiology, it refers to the movement of liquids and solute s into cells by way of diffusion or osmosis. * In chemistry, it refers to the drawing of a gas or liquid into the pores of a permeable solid. * In immunology, it refers to a process in which an antigen or antibody is used to pull an analogous antigen or antibody out of a solution. Compare adsorption .

8. Absorption spectroscopy
This is the use of a spectrophotometer to measure the ability of particles (solutes) in a solution to absorb light through a range of specific wavelengths. Every compound absorbs light differently, so absorption spectra can be used to identify compounds, measure concentrations, and determine reaction rates.

9. Activity coefficient
The factor by which the value of a concentration of a solute must be multiplied to determine its true thermodynamic activity.

10. Basal metabolic rate (BMR)
The amount of energy liberated per unit time (metabolic rate) determined at as complete mental and physical rest as possible, in a room at a comfortable temperature, 12 hours after the last meal. The BMR of a man of average size is about 2000 food calories per day. BMR is lower in elderly subjects both on an absolute basis and per unit body weight. BMR falls by about 10% between 20 to 60 years of age. However, if the changes in body composition that comes with aging is taken into consideration, the BMR of the elderly may not be that much lower.
