Ideally, when a thermometer is used to measure the temperature of an object, the temperature of the object itself should not change. however, if a significant amount of heat flows from the object to the thermometer, the temperature will change. a thermometer has a mass of 33.0 g, a specific heat capacity of c = 804 j/(kg c°), and a temperature of 15.4 °c. it is immersed in 149 g of water, and the final temperature of the water and thermometer is 56.0 °c. what was the temperature of the water in degrees celsius before the insertion of the thermometer?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
