To analyze the experiment used to determine the properties of an electron. In 1909, Robert Millikan performed an experiment involving tiny, charged drops of oil. The drops were charged because they had picked up extra electrons. Millikan was able to measure the charge on each drop in coulombs. Here is an example of what his data may have looked like. Based on the given data, how many extra electrons did drop C contain? Express your answer as an integer.

The drops were charged because they had picked up extra electrons. Millikan was able to measure the charge on each drop in coulombs. Here is an example of what his data may have looked like.

 Drop        Charge (C)

 A             -3.20 × 10⁻¹⁹

 B             -4.80 × 10⁻¹⁹

 C             -8.00 × 10⁻¹⁹

 D             -9.60 × 10⁻¹⁹

Based on the given data, how many extra electrons did drop C contain? Express your answer as an integer.

The extra electrons that the drop C contain are 5

Explanation:

Millikan’s oil drop experiment is used to measure the charge of an electron. Before this experiment, the subatomic particles were not accepted.

He found that all the oil drops had charges that were the multiples of . This value is the charge on 1 electron

Number of electrons excess electrons is calculated by using the formula:

For Drop C:

Charge on drop C =

Hence, the extra electrons that the drop C contain are 5

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 .
