Why is it easy for us to move our hand in the air but to do the same through a solid block of wood we need a karate expert?

We can easily move our hand in the air but to do the same through a solid block of wood we need a karate expert because, in air, there is a less force of attraction between the particles. So, very less amount of external force can break it.

When we move our hand in air we can easily?

Answer:Air is gas, we have learned that gas particles of less inter-molecular force of attraction and Maximum inter-molecular space. This allows the particles of Gas to move freely. That is the reason why we are able to swing our hands freely in Air.

Why can we easily move our hand in air but not through liquid or solid?

There is a lot of space between particles of gas(air) due to very weak intermolecular forces. Therefore, we can easily move our hands in air. The particles in solids are tightly packed, so we cannot move our hand in solids.

Why does gas fill completely the vessel?

Reason: Gases have a negligible intermolecular force of attraction between the particles of gas. As a result, the random motion of particles in all directions is experiencing in the vessel. Hence, the gas fills the vessel in which it is kept.

What is the meaning of karate expert?

martial artist who has attained the highest grade (dan)

What does the diffusion of gases tell us about their particles?

Solution: (a) Diffusion of gases tells us that the matter comprises of tiny particles and has space between them. The particles of matter are in constant motion.

Why diffusion in gas is quicker than liquid?

The molecules of gas have more kinetic energy than liquid molecules and are smaller. Fluid diffusion is slower because the particles move slower in a fluid. Therefore, gas particles have higher kinetic energy and travel more rapidly. Therefore, diffusion of gases is much quicker than liquid diffusion.

Why do gases spread throughout a room or through the air but liquids or solids stay together?

The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

Why does a table called a solid?

Solution 1. A wooden table has a definite shape and volume. It is very rigid and cannot be compressed i.e., it has the characteristics of a solid. Hence, a wooden table should be called a solid.

Why are gases compressible but not liquids?

Why are gases compressible but not liquids? Answer: Gases are compressible because the intermolecular space is very large in gases, whereas liquids are not compressible because in liquids, the intermolecular space is less.

What do we say Kharate in English?
