Randall D. Knight — Work, Heat, and the First Law of Thermodynamics: Problem 23
A 40 g thermometer is used to measure the temperature of 150 mL of water. The specific heat of the thermometer, which is mostly glass, is 750 J/kg K, and its reads 22°C while lying on the table. After being completely immersed in water, the thermometer’s reading stabilizes at 70.5°C. What was the actual temperature of water before it was measured?
📝 Solution Approach
Given: 40 g, 750 J, 22°C, 70.5°C
