A gas occupies a 40.0 mL at 50 K. What volume does it occupy at 300K?

Chemistry

pickupchik [31]2 years ago

Answer:

B

Explanation:

Recall the ideal gas law:

\displaystyle PV = nRT

Because pressure and amount is kept constant while volume and temperature changes, we can rearrange the formula as:

\displaystyle \frac{V}{T} = \frac{nR}{P}

The right-hand side is simply some constant. In other words:

\displaystyle \frac{V_1}{T_1}= \frac{nR}{P} = \frac{V_2}{T_2}

Substitute in known values and solve:

\displaystyle \begin{aligned} \frac{(40.0\text{ mL})}{(50\text{ K})} & = \frac{V_2}{(300\text{ K})}\\ \\ V_2 & =240\text{ mL} \end{aligned}

In conclusion, our answer is B.

How much energy is required to vaporize 14.27 grams of water at its<br> boiling point? *
laila [671]

Energy required to vaporize : 32.3 kJ

<h3>Further explanation </h3>

The heat to change the phase can be formulated :

Q = mLf (melting/freezing)

Q = mLv (vaporization/condensation)

Lf=latent heat of fusion

Lv=latent heat of vaporization

Mass of water = 14.27 g

Latent heat of vaporization ( boiling point of 100 ºC) :  2260 J/g

Energy required :

\tt Q=m.Lv\\\\Q=14.27\times 2260\\\\Q=32250.2~J\approx 32.3~kJ
