What is the relationship between the internal energy of a substance and its particle movement?

1 answer:

6 0

Answer: The closeness, arrangement and motion of the particles in a substance change when it changes state. Materials are a store of internal energy , due to the motion of particles and the chemical bonds between them. When a substance is heated, its internal energy increases: the movement of its particles increases.

A torsion balance has a sensitivity requirement (SR) of 4.5 mg. What is the MWQ of this balance if the maximum error permitted i

dybincka [34]

Explanation:

MWQ means the minimum weighable quantity.

Mathematically, MWQ = $\frac{Sensitivity}{1 - \text{fraction of accuracy}}$

or, MWQ = $\frac{sensitivity}{\text{fractional error}}$

It is given that sensitivity is 4.5 mg and maximum permitted error is 3.6%.

Therefore, fraction error = $\frac{3.6}{100}$ = 0.036

Hence, we will calculate MWQ as follows.

MWQ = $\frac{sensitivity}{\text{fractional error}}$

= $\frac{4.5 mg}{0.036}$

= 125 mg

Thus, we can conclude that the MWQ of the given balance is 125 mg.
