Question

d) wo lan easily move our hand in oo
but to do the home through a solid black
of wood we mood a karate expect​

Answer 1

Answer:

we can easily move our hand in air and water because it has low intermolecular force of attraction and high intermolecular spaces and these 2 states have high kinetic energy . It does not have a fixed shape so it is easily compressible whereas a solid block of wood has high intermolecular force of attraction low intermolecular spaces . it has a definite shape and pattern so it is hard to compress or deform .

pls mark as brainliest

Answer 2

Air is a gas, it has more space in between particles. But solid block of wood is rigid, hence it is difficult to move our hands through it.
