Question

We can easily move our hand in air but
to do the same through a solid black
of wood we need a karate expert .(give a proper reason)​

Answer 1

Answer:

because air molecules are very loosely packed

and force of attraction is very low between atoms

but in case of wood molecules are very close to each other and have very high attraction....

Please follow me

Answer 2

Hey guys your answer is here...

Yes this is right that we can move our hand in air easily but not on a solid black of wood this is because the particles of gas are farthest and the intermolecular force of attraction between them are very small. therefore it is easy to move our hand . But in the wooden block the particles are very closest and the intermolecular force of attraction are very large. Therefore we have to need more force than wooden block force.
