Predict the sign of the entropy change for each of the following processes. Justify your answers. a) Solid sugar is added to water to form a solution.

b) Iodine vapor condenses on a cold surface to form crystals.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
