Q
Q: A thermometer reads 25.0 °C with an uncertainty of ±0.5 °C. What is the range of possible temperatures?
Solution:
Range = 25.0 ± 0.5 °C = 24.5 °C to 25.5 °C.
Steps: 5
Show Steps
Step 1: Identify the temperature reading from the thermometer, which is 25.0 °C.
Step 2: Identify the uncertainty given, which is ±0.5 °C.
Step 3: To find the lower limit of the temperature range, subtract the uncertainty from the reading: 25.0 °C - 0.5 °C = 24.5 °C.
Step 4: To find the upper limit of the temperature range, add the uncertainty to the reading: 25.0 °C + 0.5 °C = 25.5 °C.
Step 5: Combine the lower and upper limits to express the range of possible temperatures: 24.5 °C to 25.5 °C.
