Students asked to measure the temperature of a reaction beaker recorded the following temperatures. 103.7°c, 108.4°c, 105.8°c, 104.6°c the actual temperature is 105.1°c. which measurement is the most precise

The measurement which is the most precise is 104.6 °C.

Explanation:

The measurement which is most precise must be very close to the actual value of the temperature.

Thus, the unit which have less value of the |Δx| (error) must be most precise.

Thus,

Actual value = 105.1 °C

Value = 103.7 °C

|Δx| = 1.4 °C

Value = 108.4 °C

|Δx| = 3.3 °C

Value = 105.8 °C

|Δx| = 0.7 °C

Value = 104.6 °C

|Δx| = 0.5 °C

Thus, The measurement which is the most precise is 104.6 °C.
