Perfectly, when a thermometer is utilized to measure the temperature of an object, the temperature of the object itself must not change. However, if a important amount of heat flows from the object to the thermometer, the temperature will change. A thermometer has a mass of 33.4 g, a specific heat capacity ofc = 832 J/(kg C°), and a temperature of 19.2 °C. It is immersed in 145 g of water, and the final temperature of the water and thermometer is 67.8 °C. What was the temperature of the water in degrees Celsius before the insertion of the thermometer?
