Chemistry(A)

1. A,is the symbol for relative atomic mass

2. absolute zero(0K)

2.1. Atoms and molecules in crystals are effectively motionless

2.2. Lowest temperature on the absolute

2.2.1. Kelvin temperature

2.3. A plot of the volume of a gas against temperature at constant pressure is a straight line which on extrapolation(estimation) cuts the temperature axis at -273.15degreeC

2.4. Gases appear to behave as if they would have zero volume at absolute zero---non-existent ideal gas

2.5. In practice, real gases changed state and occupy a definite volume before absolute zero is reached.

2.6. Defined by setting the triple point of water at 273.16K

2.6.1. Temperature and pressure at which the material can coexist in all three phases (solid, liquid and gas) in equilibrium. Specifically the triple point of water is 273.16 K at 611.2 Pa.

3. absorption of liquids and gases

3.1. Happens when a fluid soaks into the pores of a material
