Compare the properties of solids, liquids, and gases by completing the following: Compressibility solid liquid gas
shusha [124]

Answer:

Property

Solid

Liquid

Gas

1. Shape and volume

They have a definite shape as well as definite volume.

They have a definite volume but no definite shape.

They have neither a definite shape nor a definite volume.

2. Compressibility

Solids are completely incompressible.

Liquids are almost incompressible.

Gases are highly compressible.

3. Rigidity/Fluidity

Solids possess rigidity.

Liquids can flow, therefore they possess fluidity which is lower than that of gases

Gases flow more easily than liquids and thus have the highest fluidity.

4. Energy

Their particles have minimum energy.

Their particles have energy higher than those of solids.

Their particles have highest energy.

5. Density

They have high density.

Their density is lower than those of solids but much higher than those of gases.

They generally have very low densities.

6. Diffusion

They normally do not show the property of diffusion although some rare examples of diffusion of one solid into another are known.

They show the property of diffusion. As a result, solids, liquids and gases all can diffuse into liquids.

They diffuse very rapidly. The rate of diffusion of a gas is, however, inversely proportional to the square root of its density. Thus, lighter gas diffuses more rapidly than the heavier one.

(b) (i) Rigidity : It is the property which helps a substance to retain its shape when force is % applied to it. Solids are rigid while gases, and liquids are not.

(ii) Compressibility: The particles of matter can be compressed or reduced in volume by applying force or pressure. Gases are highly compressible.

(iii) Fluidity : It is the tendency of a substance to flow. Liquids and gases possess fluidity while solids are rigid.

(iv) Filling a gas container: The molecules of a gas move in all directions and due to negligible interparticle force of attraction can fill the container.

(v) Shape: Solids have definite shape whereas liquids take the shape of the container in which they are placed and gases do not have any shape.

(vi) Kinetic energy : It is the energy possessed by the particles due to their motion. The particles of a gas have maximum kinetic energy due to free motion of gas particles in all directions.

Solids have minimum kinetic energy due to least movement of particles.

(vii) Density : Density is the mass of a substance per unit volume. Solids have highest density since their molecules are closely packed.

Calculate the standard cell emf for the reaction: ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l) Pt is used as an inert elec
Rama09 [41]

<u>Answer:</u> The standard EMF of the cell is 1.11 V

<u>Explanation:</u>

For the given chemical equation:

ClO_3^-(aq)+3Cu(s)+6H^+(aq.)\rightarrow Cl^-(aq.)+3Cu^{2+}(aq.)+3H_2O(l)

The half reaction follows:

<u>Oxidation half reaction:</u>  Cu(s)\rightarrow Cu^{2+}+2e^-;E^o_{Cu^{2+}/Cu}=0.34V    ( × 3)

<u>Reduction half reaction:</u> ClO_3^-(aq.)+6H^+(aq.)+6e^-\rightarrow Cl^-(aq.)+3H_2O(l);E^o=1.45V

To calculate the E^o_{cell} of the reaction, we use the equation:

E^o_{cell}=E^o_{cathode}-E^o_{anode}

Substance getting oxidized always act as anode and the one getting reduced always act as cathode.

Calculating the E^o_{cell} using above equation, we get:

E^o_{cell}=1.45-0.34=1.11V

Hence, the standard EMF of the cell is 1.11 V

What is the importance of the electrons?<br> (write in one paragraph)
My name is Ann [436]
Well in everything we have protons and electrons, eg. In static electrisity in a balloon when you rub the balloon on a material like your hair all the protons come off and into your hair which makes your hair go upright and funny and the ballon is desperate to get back the protons so it sticks to surfaces to gain there protons to ballance out the electrons it allready has for it to be nuteral again. Because its important for everything that can be to be nuteral
