The percent error

Solution

% Error : difference between the theoretical value and the actual value

or

% Error : Absolute Error / Accepted Value

Absolute Error = Measured Value - Accepted Value

% Error for Chemistry student  :

1. Subtract the measurement value with the accepted value

= 40 °C - 43.2 °C

= -3.2 °C

2. Divide by the accepted value, and multiply by 100

= |-3.2/43.2| x 100%

= 7.4%

Entropy measures _____. 1 point<br> A. Energy<br> B. Heat Transferred<br> C. Disorder<br> D. Force
dlinn [17]

Answer: Option (C) is the correct answer.

Explanation:

The degree of randomness or disorder is known as entropy. This means that more randomly or rapidly the molecules of a substance are moving in a container or in the Universe more will be its entropy.

For example, gases move more rapidly that solids or liquids and hence gases have high entropy.

Therefore, we can conclude that entropy measures disorder.
