Problem 2: To find out how much heat is required to bring a kettle of water to its boiling point, you are asked to calculate the specific heat of water at 61 °C. The following experimental data are available. Table 1 Specific heat of water as a function of temperature. Temperature, T Specific heat, Cp (°C) J kg-°C 22 4181 42 4179 52 4186 82 4199 100 4217 Demonstrate that your approach minimizes the error in the estimation.
