Answer:

<em>An intramolecular force is between that atoms makeup a molecule. An intermolecular force is between entire molecules. A non-polar covalent bond occurs when the electrons are equally shared between atoms.</em>

A sample of argon has a volume of 5.0 dm^3 and the pressure is 0.92 atm.
Evgesh-ka [11]

Answer:

232.9K

       

Explanation:

V₁  = 5dm³

P₁  = 0.92atm

T₂ = 30°C

V₂ = 5.7L

P₂ = 800mmHg

Unknown:

T₁ = ?

Solution:

To solve this problem, we are going to apply the combined gas law which is fusion of the avogadro's law, boyle's law and charles's law.

 Mathematically;

                   \frac{P_{1}V_{1}  }{T_{1} } = \frac{P_{2}V_{2}  }{T_{2} }

p, v and T are pressure, volume and temperature respetively

1 and 2 depicts the initial and final states.

We need to convert ;

     temperature to K and pressure into atm

T₂  = 30°C  = 273 + 30 = 303K

P₂  =  800mmHg;

         760mmHg  = 1 atm

           800mmHg  = \frac{800}{760}  = 1.05atm

   Input the variables and solve;

      \frac{0.92 x 5}{T}  = \frac{1.05 x 5.7}{303}

    T  = 232.9K
