Answer: 373 mL
Explanation:
Since there is no change in pressure, the formula: V / T = V / T can be used.
However, you must first convert the temperatures to Kelvin by adding 273 to them:
(19 + 273) = 292K and (90 + 273) = 363K.
Now, plug in: V / 292 = 464 / 363 → V = 373 mL :)
Answer:
Both roots are imaginary roots.
Explanation:
Consider these things:
If we try to solve x²+1 = 0, notice that we aren't able to solve the equation in Real Number system because there are no negative outputs for quadratic function.
Remember that quadratic function has range greater or equal to the max-min value.
x-axis plane represents the solutions of that equation. If a graph intersects x-axis plane then it has a solution.
While a graph that doesn't have any intersects on x-plane, it means that the equation for that graph doesn't have real solutions but imaginary solutions.
As you may notice some of parabola graph has one intersect, two intersects or none. One intersect is one solution to the equation — Two intersects are two solutions of the equation and lastly, no intersects mean that no real solutions and remain only imaginary solution.

The inner diameter for a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k is 1.45 m
<h3>What is Stack Height ?</h3>
Stack height means the distance from the ground-level elevation at the base of the stack to the crown of the stack.
If a stack arises from a building or other structure, the ground-level elevation of that building or structure will be used as the base elevation of the stack.
Given is a steel stack that exhausts 1,200 cu.m/min of gases
P= 1 atm and
T= 400 K
maximum expected wind speed at stack height of 12 m/s
The formula for the diameter of chimney
![\rm d=\sqrt{\dfrac{4Q}{\pi v} }](https://tex.z-dn.net/?f=%5Crm%20d%3D%5Csqrt%7B%5Cdfrac%7B4Q%7D%7B%5Cpi%20v%7D%20%7D)
Q =1200 cu.m/min
= 1200 * 0.0166 = 19.92 cu.m/sec
Velocity = 12m/s
![\rm d=\sqrt{\dfrac{4\times 19.92}{3.14*12} }\\](https://tex.z-dn.net/?f=%5Crm%20d%3D%5Csqrt%7B%5Cdfrac%7B4%5Ctimes%2019.92%7D%7B3.14%2A12%7D%20%7D%5C%5C)
d= 1.45 m
Therefore The inner diameter for a steel stack that exhausts 1,200 m3/min of gases at 1 atm and 400 k is 1.45 m.

Answer : The temperature of liquid is, 369.9 K
Explanation :
The Clausius- Clapeyron equation is :
![\ln (\frac{P_2}{P_1})=\frac{\Delta H_{vap}}{R}\times (\frac{1}{T_1}-\frac{1}{T_2})](https://tex.z-dn.net/?f=%5Cln%20%28%5Cfrac%7BP_2%7D%7BP_1%7D%29%3D%5Cfrac%7B%5CDelta%20H_%7Bvap%7D%7D%7BR%7D%5Ctimes%20%28%5Cfrac%7B1%7D%7BT_1%7D-%5Cfrac%7B1%7D%7BT_2%7D%29)
where,
= vapor pressure of liquid at 373 K = 681 torr
= vapor pressure of liquid at normal boiling point = 760 torr
= temperature of liquid = ?
= normal boiling point of liquid = 373 K
= heat of vaporization = 40.7 kJ/mole = 40700 J/mole
R = universal constant = 8.314 J/K.mole
Now put all the given values in the above formula, we get:
![\ln (\frac{760torr}{681torr})=\frac{40700J/mole}{8.314J/K.mole}\times (\frac{1}{T_1}-\frac{1}{373K})](https://tex.z-dn.net/?f=%5Cln%20%28%5Cfrac%7B760torr%7D%7B681torr%7D%29%3D%5Cfrac%7B40700J%2Fmole%7D%7B8.314J%2FK.mole%7D%5Ctimes%20%28%5Cfrac%7B1%7D%7BT_1%7D-%5Cfrac%7B1%7D%7B373K%7D%29)
![T_1=369.907K\approx 369.9K](https://tex.z-dn.net/?f=T_1%3D369.907K%5Capprox%20369.9K)
Hence, the temperature of liquid is, 369.9 K
