Ateaspoon of sugar is added to a glass of tea which is then stirred until no more crystals can be seen. another teaspoon is added and stirring is continued until no more crystals can be seen. after the first teaspoon of sugar is added, the solution is saturated unsaturated polar nonpolar

a is the answer to this question

explanation:

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.
