Students asked to measure the temperature of a reaction beaker recorded the following temperatures. 103.7°C, 108.4°C, 105.8°C, 1
zavuch27 [327]

Answer:

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

<u>|Δx| = 1.4 °C</u>

Value = 108.4 °C

<u>|Δx| = 3.3 °C</u>

Value = 105.8 °C

<u>|Δx| = 0.7 °C</u>

Value = 104.6 °C

<u>|Δx| = 0.5 °C</u>

<u>Thus, The measurement which is the most precise is 104.6 °C.</u>

Compare the freezing point of water in the aquanaut’s apartment to its value at the surface. Is it higher, lower, or the same?
Lelu [443]

Answer:

Freezing Point - Lower

Boiling Point - Higher

Solid- liquid transition line in the phase diagram has a negative slope, but the liquid-gas transition line has a positive slope. Since there is more air pressure at 100m it will take less to freeze the water but more to boil it since it requires a larger temperature under larger pressures

A racing car on a straight accelerates from 100mph to 316 mph in three seconds what is the acceleration?
omeli [17]

Answer:

72mph/sec

Explanation:

The car goes from 100mph to 316mph in three seconds. Meaning it increases its speed by (316 - 100)mph in three seconds. That is 216 mph increase in three seconds. So, we divide the speed increase by the amount of time the increase occurred over. We get:

216mph / 3sec = 72mph/sec, our final answer

Hope it made sense. I would appreciate Brainliest, but no worries.
