To find 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 specific heat of water is given as a function of time in Table 1. Table 1 Specific heat of water as a function of temperature. Temperature, T Specific heat, C, (C) kg - C 4181 4179 4186 4199 4217 Determine the value of the specific heat at 7 = 61"C using the direct method of interpolation
