Explain how the following scenario might have influenced the development of the antibiotic penicillin. Situation: In 1897, The Institut Pasteur receives the thesis of Duchesne regarding the Penicillium mold, “Contribution to the study of vital competition in micro-organisms: antagonism between moulds and microbes,” and decides to publish it instead of ignore it.

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.

0.11 m/s and 0.28 m/s should be correct

the right answer is 0.3 meters per second
