This follows a simple conversion technique. Basically what the question is trying to say here is to convert 29.1 inHg to mmHg. 1 inHg is equal to 25.4 mmHg so 29.1 inHg would be equal to
which when evaluated turns out to be:

Answer:
Relative error = 0.35
observed value = 8.775
Explanation:
given data:
Actual value = 13.5 L
Percentage of error=35%
Relative error can be determined as follow:
![Relative\ error = \frac{absolute\ error}{actual\ value}](https://tex.z-dn.net/?f=Relative%5C%20error%20%3D%20%5Cfrac%7Babsolute%5C%20error%7D%7Bactual%5C%20value%7D)
Absolute error = actual value - observed value
Percentage of error ![= relative error*100](https://tex.z-dn.net/?f=%3D%20relative%20error%2A100)
Then relative error ![= \frac{percentage\ of\ error}{100}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7Bpercentage%5C%20of%5C%20error%7D%7B100%7D%20)
Relative error ![= \frac{35}{100} =0.35](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B35%7D%7B100%7D%20%3D0.35)
Then absolute error = ![relative\ error\times actual\ value](https://tex.z-dn.net/?f=relative%5C%20error%5Ctimes%20actual%5C%20value)
![=0.35\times 13.5 = 4.725](https://tex.z-dn.net/?f=%3D0.35%5Ctimes%2013.5%20%3D%204.725)
Therefore experimental measurement value(observed value)
= actual value - absolute error
=13.5 - 4.725 = 8.775
The most important state in determining the state of a substance is
temperature. This is because the kinetic energy of a substance's
molecules depend on its temperature. For example, an increase in
temperature speeds up the movement of molecules. A decrease in
temperature slows down the movement of molecules.
This is
important because by increasing or decreasing a substance's temperature,
you are also adding or removing energy from it. And when a substantial
amount of energy has been added or removed, a substance can change its
state from solid > liquid > gas or the other way around.
