When you drop a sugar cube in a glass of water, at first the water doesn’t taste sweet. later, it tastes very sweet. eventually, the water will taste equally sweet throughout. what term explains molecule movement to maintain a balance?

Diffusion

Explanation:

Diffusion: when sugar is introduced in water, the particles will spread in an irreversible process (dilution) until the concentration is uniform (or the same in any point of the container). When this uniformity is reached, there is an equilibrium state.

As the process is irreversible, sweet taste will not change with time and equilibrium will be maintained.  

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
