Study Cards on accommodate, molecules, energetic
- The amount of motion of the molecules
- The number of holes that happen to be present
- Number of sufficiently energetic jumps is reduced --> The molecules have less thermal (Brownian) motion, so that means jumps will be less frequent
- The amount of space to accommodate molecules that have jumped, has become less --> The lower amount of thermal motion will also mean that the molecules will move closer together, there is simply less space needed to accommodate all the motion. Therefore, the density will increase and the molar volume will decrease. Since the molecules themselves will not occupy any less space, this means that the free volume is reduced.
Far away (thin viscous liquids, such as water or ethanol), below 30% w/w in sugar solutions --> Arrhenius
