<h2>The answer is - D. soluble</h2><h2 /><h3>Explanation: A physical property is a property that can be observed without a chemical reaction taking place. Solubility is a physical property because it does not involve a chemical reaction taking place since the substance that dissolves still remains the same substance.</h3>

The new volume of the bag will be 789.5 mL.

<u>Explanation:</u>

As per the Charles law, at constant pressure the volume of the gas is directly related to its temperature in Kelvin (K). That is as the temperature increases, the gas expands and vice-versa.

$\frac{V1}{T1} = \frac{V2}{T2}\\

V1 = 250 ml

V2 = ?

T1 = 19° C

T2 = 60° C

Now we have to rewrite the equation to get the new volume as,

V2 = $\frac{V1T2}{T1}

    =$\frac{250\times60}{19}

<em>     </em>= 789.47 ≈ 789.5 ml.

So the new volume of the bag will be 789.5 mL.

What does the kinetic theory explain?
olya-2409 [2.1K]
I believe the correct answer from the choices listed above is the third option. The kinetic theory explains that heat is due to the motion of molecules. Temperature is the measurement used to measure heat and is directly proportional to the average kinetic energy of the molecules.
