An object has a -8 c charge. the object breaks into two pieces. one piece has a charge of -2 c. what is the exact charge (in c) of the other piece? do not include units with your answer.

As we know the property of charge that charge is always conserved

so we can say

here we know that total charge is

and we also know that

from above equation we can say

so the other charge will be -6 C

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
