Assume the specific heat of tea is 4180 J/kg Cand the specific heat of aluminum is 900 J/kg C. Part A What is the highest possible temperature of the spoon when you finally take it out ofthe cup? Express your answer using two significant figures. Submit My Answers Give Up Part B What is the temperature of the tea at that time? Express your answer using two significant figures.Explanation / Answer
according to thermal equilibrium heat energy lost by a body is equal to heat energy gained by other body so
the heat energy gained by spoon is 670C (Q= MC delta t)
Tea temperature is when spoon having temperature is 670C is 130C
