Explanation:

Anything that occupies space and has mass is called matter.

(a) Inter particle space

Solids - Atoms of a solid substance are closely packed with each other due to which there is very less or no inter particle space.
Liquids - Atoms of a liquid are little loosely packed due to which there is some inter particle space.
Gases - Atoms of a gas are very loosely packed due to which there is large inter particle space.

(b) Inter particle force of attraction

Solids - Atoms of a solid are attached to each other by strong force of attraction.
Liquids - Atoms of a liquid have slightly less force of attraction as compared to a solid substance.
Gases - Atoms of a gas have Vander waal forces. Hence, there is no inter particle force of attraction between atoms of a gas.

(c) Particle motion

Solids - There is low or negligible particle motion between atoms of a solid.
Liquids - There is high particle motion as compared to that present in a solid.
Gases - There is very high particle motion as compared to solids and liquids.

2.61 kilograms of water in a container have a pressure of 200 kPa and temperature of 200°C . What is the volume of this containe

Arisa [49]

<u>Answer:</u> The volume of the container is $2.8497m^3$

<u>Explanation:</u>

To calculate the volume of water, we use the equation given by ideal gas, which is:

$PV=nRT$

or,

$PV=\frac{m}{M}RT$

where,

P = pressure of container = 200 kPa

V = volume of container = ? L

m = Given mass of water = 2.61 kg = 2610 g (Conversion factor: 1kg = 1000 g)

M = Molar mass of water = 18 g/mol

R = Gas constant = $8.31\text{L kPa }mol^{-1}K^{-1}$

T = temperature of container = $200^oC=[200+273]K=473K$

Putting values in above equation, we get:

$200kPa\times V=\frac{2610g}{18g/mol}\times 8.31\text{L kPa }\times 473K\\\\V=2849.7L$

Converting this into cubic meter, we use the conversion factor:

$1m^3=1000L$

So, $\Rightarrow \frac{1m^3}{1000L}\times 2849.7L$

$\Rightarrow 2.8497m^3$

Hence, the volume of the container is $2.8497m^3$

GarryVolchara [31]

The given question is incomplete. The complete question is :

Welding is an industrial process that is used to join pieces of metal. A certain mixture of gases used in welding is composed of carbon dioxide and argon. The partial pressure of carbon dioxide is 0.080 atm and the partial pressure of argon is 0.24 atm. What is the total pressure of the mixture.

Answer: 0.32 atm

Explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

$p_{total}=p_{CO_2}+p_{Ar}$
