During titration, it is very common to have some naoh spilled to the inside wall of erlenmeyer flask. ideally, these spilled naoh should be washed down, but most students (if not all) did not do so. how will these naoh on the wall affect the experimental result?

since these spills will make the volume of naoh artificially higher, it will make the experimental result higher as well.
since these naoh did not have a chance to react with acetic acid, it should not affect the experimental result.
since these naoh did not have a chance to react with acetic acid in vinegar, it will make the experimental result lower.

Its the first option

Explanation:

The volume of NaOH  added will be more than that which is needed to  neutralise the acetic acid. As the result is calculated from the volume of NAOH added from the burette, the result will be higher than the true result.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
