An unknown material, m, = 0.21 kg, at a temperature of T, = 76 degrees C is added to a Dewer (an insulated container) which contains m2 = 1.1 kg of water at T, = 21 degrees C. Water has a specific heat of c,, = 4186 J/(kg-K). After the system comes to equilibrium the final temperature is T = 30.5 degrees C.

Question
An unknown material, m, = 0.21 kg, at a temperature of T, = 76 degrees C is added to a Dewer (an insulated container) which contains m2 = 1.1 kg of water at T2 = 21 degrees C. Water has a specific heat of c,,= 4186 J/(kg·K). After the system comes to equilibrium the final temperature is T= 30.5 degrees C. Input an expression for the specific heat of the unknown material. Cu What is the specific heat in J/(kg-K)?
