Here are the choices:

Warm air rises while cold air falls.

The warmer air contains less water vapor per unit of volume.

The warmer air contains more water vapor per unit of volume.

Moist air has lower density than dry air does.

The best answer is: <em>The warmer air contains more water vapor per unit of volume. </em>

Which state of matter (solid, liquid, or gas) has molecules that move the fastest?
Margaret [11]
Gas.

Solid is the slowest; it stays together, so the molecules don't move much.
Liquid is the middle; it stays together for the most part, but it can move.
Gas is the fastest; they can move all over the place!

A certain mass of nitrogen gas occupies a volume of 4.67 L 4.67 L at a pressure of 4.94 bar 4.94 bar . Calculate the pressure of
kumpel [21]

Answer : The final pressure of gas is, 3.27 bar.

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

P\propto \frac{1}{V}

or,

P_1V_1=P_2V_2

where,

P_1 = initial pressure = 4.94 bar

P_2 = final pressure = ?

V_1 = initial volume = 4.67 L

V_2 = final volume = 7.05 L

Now put all the given values in the above equation, we get:

4.94bar\times 4.67L=P_2\times 7.05L

P_2=3.27bar

Therefore, the final pressure of gas is, 3.27 bar.
