why is it essential to know the water temperature in this experiment- to find the vapor pressure of the water

Chemistry
1 answer:
Oksi-84 [34.3K]3 years ago
5 0

Answer:

Vapour pressure of a liquid varies with temperature

Explanation:

The vapour pressure of any liquid is directly proportional to the temperature of the liquid. This implies that, as the temperature of the liquid increases, the vapour pressure increases likewise and vice versa.

Since the vapour pressure of liquid varies with the temperature of the liquid, it is essential to know the water temperature in the experiment to determine the vapour pressure of water.

What is the difference between viruses and bacteria? Write complete sentences?
andrew-mc [135]

Answer:

While both can cause disease, viruses are not living organisms, whereas bacteria are. Viruses are only "active" within host cells which they need to reproduce, while bacteria are single-celled organisms that produce their own energy and can reproduce on their own. Bacteria serve many vital roles in nature outside of being infectious.

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.
