![The image displays a graphic of a thermometer alongside temperature labels. On the left side, two lines of black text read '60°C' on the top line and '0°C' on the bottom line. To the right of the text is a vertical thermometer. The thermometer has a black outline and a red bulb at the bottom. A red column of liquid rises from the bulb inside the thermometer tube, extending to a level approximately halfway up the scale. Small tick marks are visible along the side of the thermometer, indicating a temperature range that aligns with the labels, from 0°C at the bottom to 60°C at the top.](.imb-c46h-20250304/7686be7eaf67b69521fb407818b2a618adcc65df726c669e0d945222c0f15963.jpg)
