The difference between two temperature readings in an experiment was 9. Which of these could be the temperature
readings?
15 and 6
-5° and 4
-1° and 9
2 and 11"
Answers
15-6=9
4-(-5)=4+5=9
11-2=9
This could be the temperature readings.
9-(-1)=9+1=10
This cannot be the temperature reading.
Answer:
The answer is option (B). -5° and 4°
step-by-step explanation:
When two independent temperature data are subtracted, or when determining the total of temperature rise or fall, the result is a drop in temperature, also referred to as a delta temperature (T). Temperature gradient is a measurement of the percentage composition of internal energy between two bodies as compared to absolute temperature. Simply said, temperature is a measurement of how hot or cold a thing is. In general, things that seem hotter have greater temperatures, and vice versa.
In an experiment, the variance between two temperature readings was 9.
What of these might make a difference?
difference are
(A). 15° and 6°
= 15° - (-6°)
= 15° + 6°
= 21°
(B). -5° and 4°
= 4° - (-5°)
= 4° + 5°
= 9°
(C). -1° and 9°
= 9° - (-1°)
= 9° + 1°
= 10°
(D). 2° and 11°
= 11° - (-2°)
= 11° + 2°
=13°
Therefore the answer is option (B). -5° and 4° = 9°
