The correct answer should be option A.
'IV' is not true because temperature does not rise during melting, but remains constant.
the correct answer is A option iv is wrong as temperature remains constant during melting
With the options there, none of the answers is correct. From the Question, option A is II and III and not I and III.
Also option D is II, III and IV and not II and IV.
I suggest the option should be updated rightly.
Thank you.
The answer is meant to be constant temperature at melting point and increase in temperature before melting begins as the temperature of a pure solid at it’s melting point doesn’t increase because all the heat is absorbed to break intermolecular bonds.
I hope this is rectified quickly, Thanks 😊
please, can you explain how you arrived at option B cause it really looks strange
Temperature is steady and increasing simultaneously, how possible
Come its like you boys in this joint didnt attend an educational institution. Pls yan me how thats the answer
