Question

requiring the measurement to be
to the tenths place (0.1 °c).
ly at the following thermometer and
use it to answer the question.
how should you record the temperature
measurement for this thermometer?
25 °c
24.0 °c
25.0 °c
24 °c

Explanation:

Step1: Analyze the thermometer scale

The thermometer has markings at 10, 20, 30 °C. The interval between 20 and 30 °C is divided into 10 small divisions (since from 20 to 30, there are 10 spaces to reach 30). So each small division is $\frac{30 - 20}{10}= 1$ °C? Wait, no, wait. Wait, looking at the red liquid, the meniscus is at a position. Wait, maybe the scale between 20 and 30: let's see, the red line is at 24? Wait, no, wait the options have 24.0. Wait, maybe the scale: from 20 to 30, how many divisions? Let's count the lines. From 20 to 30, there are 10 small lines (since 20, then 9 lines to 30? Wait, no, the image shows that between 20 and 30, there are 10 intervals? Wait, the red liquid is at 24.0? Wait, no, wait the options: 24.0, 25.0, etc. Wait, the thermometer's scale: let's see, the red column is at 24.0? Wait, maybe the main scale: each major division (like 20 to 30) is 10 °C, and each minor division is 1 °C? No, wait the problem says to record to the tenths place (0.1 °C). So we need to estimate to one decimal place. Looking at the thermometer, the meniscus is at 24.0 °C? Wait, no, wait the red line: let's see, the 20 is at the bottom, 30 at the top. The red liquid is at 24.0? Wait, maybe the scale between 20 and 30: if there are 10 divisions between 20 and 30, each division is 1 °C, but we need to record to 0.1 °C. Wait, no, maybe the thermometer has a precision of 0.1 °C? Wait, the options: 24.0 is to the tenths place. Let's check the position: the red line is at 24.0? Wait, maybe the correct reading is 24.0 °C. So the answer is 24.0 °C.

Answer:

24.0 °C
