question 4 of 25
a thermometer measures temperature to the nearest 0.5°c. which measurement shows an appropriate level of precision for the thermometer?
a. 16°c
b. 21.55°c
c. 16.0°c
d. 20°c

Explanation:

Step1: Understand precision requirement

The thermometer measures to nearest 0.5°C. So measurement should be in increments of 0.5.

Step2: Analyze options

• Option A: 16°C can be written as 16.0°C which is a multiple of 0.5.
• Option B: 21.55°C is not a multiple of 0.5.
• Option C: 16.0°C is a multiple of 0.5.
• Option D: 20°C can be written as 20.0°C which is a multiple of 0.5. But we need to consider the precision - 16.0°C shows the precision of the thermometer better as it explicitly shows the decimal place consistent with the precision of 0.5°C.

Answer:

C. 16.0°C
