If most objects are made up of free space then why can we put our hands through a book or wall?

I suppose you mean to ask why we can't go through obstacles.

Any atom is surrounded by an electronic cloud. When two atoms get close to each other, the electronic clouds repel each other, preventing them from interpenetrating each other. That same phenomenon, on a larger scale, prevents us from going through matter.

Calculate the number of atoms in 4.8 dm^3 of neon gas at rtp

WINSTONCH [101]

No of atoms in 4.8 dm³ of neon gas is determined in the following way.

Explanation:

We have given

Neon Gas=4.8dm³

At STP

1 mole of an ideal gas occupies 22.4 L(dm³) of volume.

which means that number of molecules occupy 22.4 L of volume.

4.8 dm³x 1 mole/22.4 dm³ = 0.214 moles Neon

0.214 moles x 6.02x10²³ atoms/mole = 1.29x10²³ atoms of Neon

No of Atoms in 4.8dm3 neon gas =1.29x10²³ atoms of Neon

How is the kinetic energy of the constituent particles of any matter affected by a change in temperature?

SpyIntel [72]

Answer:

Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. ... Individual particles in liquids and gases have no fixed positions and move chaotically.
