Answer 1

Answer:

Explanation:

In the first picture, we can see that it is a Key. Fact: We call key as clé in french. So, let us learn what is IMFA.

IMF or Intermolecular Force of Attraction is actually the capability of a particular state of matter (example solid, liquid, gas, plasma or BEC Bose Einstein Condensate) to hold the particles tightly.

Carry out this activity :-

• Take a hammer, a key and a branch of tree.
• Now, bang the hammer in (1) key (2) branch of a tree.
• Now, what can you see, is listed here :-

Observations:-

1. The key does not break as it is made of iron
2. The tree branch breaks.

This is because the Inter molecular forces of attraction of Iron is much high as compared to the dead/ living cells of the tree branches.

Therefore, what we can conclude is a key has more intermolecular force of attraction than a branch of a tree $.$

Answer 2

Answer :-

INTERPARTICLE FORCE OF ATTRACTION :-

• It is the force of attraction exerted between two atoms, molecules, or ions. It is highest in solids and the least in gases.

We are given a key and a branch of a tree and are asked to compare the interparticle force of attraction, so first let's take a key and ride a bike or a bicycle on it, we'll observe that there is not change in the key except its shape changes, there is no crack or damage to the key and if any it can be easily welded and make it good as earlier. It is so because key is a solid, so the interparticle forces between the key are very very strong which helped the key to be very strong and unbroken. Now let's take a branch of a tree and do the same activity, run a vehicle on it, if you the branch breaks and turns into smaller pieces because the particles in the branch of tree are not that strong, though a branch is a solid, they are no that powerful bonds like that of the key. This is the reason why the branch breaks and there is no damage to the key and thus we can conclude by saying that a key has more interparticle force of attraction than a branch of a tree.
