A hungry bat finds the mother lode of flying insects between the headlights of two bicycles cruising towards each other through Busse Woods Forest Preserve. The bikes are initially 200 meters apart and one has a speed of 8 m/s while the other has a speed of 10 m/s. The bat flies at a constant speed of 20 m/s, but flies back and forth between the two bicycles continuously. Determine the total distance the bat has traveled when the bicycles meet.

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.
