If 4.65 LL of CO2CO2 gas at 22 ∘C∘C at 793 mmHg mmHg is used, what is the final volume, in liters, of the gas at 35 ∘C∘C and a p
otez555 [7]

Answer:

About 7.9 L.

Explanation:

We can utilize the ideal gas law. Recall that:

\displaystyle PV = nRT

Because the amount of carbon dioxide does not change, we can rearrange to formula to:
\displaystyle \frac{PV}{T}= nR

Because the right-hand side stays constant, we have that:
\displaystyle \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} = nR

Hence substitute initial values and known final values:
\displaystyle \begin{aligned} \frac{(793\text{ mm Hg})(4.65 \text{ L})}{(22 \text{ $^\circ$C})} & = \frac{(743 \text{ mm Hg})V_2}{(35\text{ $^\circ$C})} \\ \\ V_2 & = 7.9\text{ L}\end{aligned}

Therefore, the final volume is about 7.9 L.

A 45 kg box is sitting on a window ledge 2.0 m above the ground. What is the potential energy of the box?
Travka [436]

Answer:

<h3>The answer is 900 J</h3>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

PE = 45 × 10 × 2

We have the final answer as

<h3>900 J</h3>

Hope this helps you
