N = {Odd numbers less than 10) are subsets of
E = {Natural numbers from 1 to 12)
(i) List the members of set M, N and E.
(ii) Draw a venn diagram to represent this information
(iii) From the diagram, find;
(A) MUN
(7) MON​

answer; /// i believe that the correct answer is (50%);

the correct answer is d

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
