1. A given mass of air has a volume of 6.00 L at 80.0°C. At constant pressure, the temperature is
earnstyle [38]

3 L will be the final volume for the gas as per Charle's law.

Answer:

Explanation:

The kinetic theory of gases has two significant law which forms the backdrop of motion of gases. They are Charle's law and Boyle's law. As per Charle's law, the volume of any gas molecule at constant pressure is directly proportional to the temperature of the molecule.

V∝ T

Since, here two volumes are given and at two different temperatures with constant pressure. Then as per Charle's law, the relation between the volumes of air at different temperature will be

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

So in this case, V1 = 6 L and T1 = 80° C. Similarly, T2 = 40° C. So we have to determine the V2.

\frac{6}{80}=\frac{V_{2} }{40}

V_{2}=\frac{6*40}{80}=3 L

So, 3 L will be the final volume for the gas as per Charle's law.

Which factor explains why coal dust in an enclosed space is more explosive than coal dust blown outdoors into an open space ? A.
leonid [27]

Answer:

Option C:- Concentration

Explanation:

Coal dust explosion can cause lots of damage. To avoid

this, the amount or concentration of coal dust per unit

volume or MEC is measured with the various conditions

of coal storage such as the particle size, moisture of coal,

degree of dispersion and delayed time of ignition source

to prevent the coal dust explosion which aims to study

and design the explosion safety measures for coal dust

handing installations. The results present that moisture

content in coal has more effect on dust explosion. The

smaller size of particle, low moisture in coal and high

coal dust dispersion can increase the possibility or risk of

dust explosion.
