A 254-rad dose of radiation is administered to a patient in an effort to combat a cancerous growth. Assume that all of the energy deposited is absorbed by the growth. (Use 4186 J/kg · °C for the specific heat of water.) (a) Calculate the amount of energy delivered per unit mass. J/kg (b) Assuming the growth has a mass of 0.25 kg and a specific heat equal to that of water, calculate its temperature rise. Your response differs from the...

Part A IN gams: In an experiment, a 0.270-kg piece of ceramic superconducting material at 17 °C is placed in liquid nitrogen at its boiling point (−195.8 °C) to cool. The nitrogen is in a perfectly insulated flask that allows the gaseous N2 to escape immediately. How much mass of liquid nitrogen will be boiled away?
