Question

the temperature at 300 seconds (5 minutes) is the final temperature of both the metal and the water. record it to the nearest 0.1°c in the data table. initial temperature of metal = 100 °c initial temperature of water = 22.5 °c final temperature of both = °c

Explanation:

Step1: Analyze the thermometer scale

The thermometer has major marks at 22, 23, 24, 25, 26, 27 °C. Between each major mark, there are smaller divisions. Let's assume each major mark (1 °C) is divided into 10 smaller divisions, so each small division is 0.1 °C.

Step2: Determine the final temperature

Looking at the thermometer, the liquid level (or the mark) is at 25.0 °C? Wait, no, wait. Wait, the red part and the scale: Wait, the scale in the magnified view: the lower scale (the one with the numbers 22,23,24,25,26,27) – let's check the position. Wait, the vertical line is at 25? Wait, no, maybe I misread. Wait, the thermometer scale: let's see, the numbers are 22,23,24,25,26,27. The black vertical line is at 25? Wait, no, maybe the scale is such that each major division (between 22 - 23, 23 - 24, etc.) has 10 minor divisions. So from 24 to 25 is 10 divisions, each 0.1 °C. Wait, the red block and the scale: the final temperature mark is at 25.0? Wait, no, wait the problem says "record it to the nearest 0.1°C". Wait, looking at the magnified image, the thermometer's scale: the line is at 25.0? Wait, no, maybe I made a mistake. Wait, let's re - examine. The numbers are 22,23,24,25,26,27. The vertical line (the indicator) is at 25.0? Wait, no, maybe the scale between 24 and 25: if each major division is 1 °C, and divided into 10 parts, then each part is 0.1 °C. So if the indicator is at 25.0? Wait, no, maybe the correct reading is 25.0 °C? Wait, no, wait the initial temperature of water is 22.5? Wait, no, the final temperature: the problem says "final temperature of both the metal and the water". Wait, looking at the thermometer in the image, the indicator is at 25.0 °C? Wait, maybe I misread. Wait, let's count the divisions. From 24 to 25: how many divisions? If the scale is marked with 22,23,24,25,26,27, and the vertical line is at 25.0? Wait, no, maybe the correct reading is 25.0 °C? Wait, no, perhaps the scale is such that the indicator is at 25.0. Wait, maybe the answer is 25.0 °C. Wait, let's check again. The magnified thermometer: the numbers are 22,23,24,25,26,27. The black vertical line is at 25.0? So the final temperature is 25.0 °C? Wait, no, maybe I messed up. Wait, the initial temperature of water is 22.5? No, the problem is about the final temperature. Wait, the image shows the thermometer with the indicator at 25.0? So the final temperature of both metal and water is 25.0 °C (to the nearest 0.1 °C).

Answer:

25.0
