At sea level water usually boils at 100. °C and 760. mmHg pressure. On Mt Whitney, the pressure is about 560. mmHg. At what temp
erature, in degress Celsius, does water boil on Mt Whitney?
1 answer:
Answer:
91.7°C
Explanation:
We suppose you have a formula to work from. However, that is not supplied with this problem statement, so we looked one up.
The formula in the attachment is supposed to have good accuracy in the temperature range of interest. It gives vapor pressure of water in kPa, not mmHg, so we needed the conversion for that, too.
560 mmHg corresponds to about 74.66 kPa. The attached "Buck equation" formula is used to find the corresponding temperature. The exponential equation could be solved algebraically using logarithms and the quadratic formula, but we choose to find the solution graphically.
Water boils at about 91.7 °C on Mt. Whitney.

<u>Answer:</u>
<u>For a:</u> The volume of the box is 217.5 mL
<u>For b:</u> The volume of the box is 0.2175 L
<u>Explanation:</u>
The box is a type of cuboid.
To calculate the volume of cuboid, we use the equation:
where,
V = volume of cuboid
l = length of cuboid = 10.00 cm
b = breadth of cuboid = 7.25 cm
h = height of cuboid = 3.00 cm
Putting values in above equation, we get:
- <u>For a:</u>
To convert the volume of cuboid into milliliters, we use the conversion factor:
So,
Hence, the volume of the box is 217.5 mL
- <u>For b:</u>
To convert the volume of cuboid into liters, we use the conversion factor:
So,
Hence, the volume of the box is 0.2175 L
