Explain how different states of matter are distinguished from each other and how pure substance distinguish from mixtures

Physics
1 answer:
iVinArrow [24]4 years ago

Hello

The difference between the states of matter is explained as follows:
- a solid has a definite shape and a definite volume
- a liquid has a definite volume, but its shape changes depending on its container
- a gas does not have neither a definite volume nor a definite shape: both change depending on the container. In fact, a gas expands until it occupies the whole volume available.

The difference between a pure substance and a mixture is:
- a pure substance has a precise and definite chemical composition
- a mixture, instead, is a combination of two or more substances.

Assume that the pressure in a room remains constant at 1.01
Ray Of Light [21]

Answer:

Explanation:

Given

Pressure P_1=1.01\times 10^5 Pa

Volume of air V=60 m^3

Initial Temperature T_1=289 K

T_2=302 K

Initial moles is given by

PV=nRT

n_1=\frac{P_1V_1}{RT_1}

n_1=\frac{1.01\times 10^5\times 60}{R\cdot 289}

when some gas escape out

no of moles is equal to

n_2=\frac{P_2\times V_2}{R\cdot T_2}

n_2=\frac{1.01\times 10^5\times 60}{R\cdot 302}

remaining no of moles =n_1-n_2

=\frac{1.01\times 10^5\times 60}{R\cdot 289}-\frac{1.01\times 10^5\times 60}{R\cdot 302}

=\frac{1.01\times 10^5\times 60}{R}(\frac{1}{289}-\frac{1}{302})

Mass of air escape out

=(n_1-n_2)\times M

=(\frac{1.01\times 10^5\times 60}{R}(\frac{1}{289}-\frac{1}{302}))\times 28

=25.272\times 10^3\ g

m=25.272\ kg

8. A jaguar runs 4200 meters at the speed of 400 meters per minute. How
ollegr [7]

Answer:

10.5min

Explanation:

Given parameters:

Distance  = 4200m

Speed  = 400m/min

Unknown:

Time taken for this run  = ?

Solution:

Speed is the distance divided by the time taken.

   Speed  = \frac{distance }{time }  

  Time  = \frac{distance}{speed }  

 Now insert the parameters and solve;

 Time  = \frac{4200}{400}   = 10.5min
