Question

melting points of three substances A,B,C are 52 degree C, 175 degree C, 80 degree C .

Arrange them in decreasing order of interparticle force of attraction. Give reasons for your answer

Answer 1

Interparticle force of attraction B>C>A

Explanation:

As B takes larger amount of heat to melt, we see that it's interpartice force is strong and requires more energy to break.

similarly, interparticle force of A is the least.

Answer 2

Answer:

A is 52°c

B is 175°c

C is 80°c

So as per the decreasing order we know that is it arranged from Bigger to smaller amount .

Now the highest degree is 175°c ie B so it is first. Intermediate one is 80°c so second one is C and last is 52°c ie A.

B>C>A

(175>80>52)°C

THIS IS THE ANSWER. HOPE IT HELPS YOU AND PLEASE MARK IT AS BRAINLIEST...
