Question

a banana with a temperature of 17 degrees C (specific heat of banana= 3520j/kgK) and a a mass of 250g is placed in a bowl of milk with a temperature of 8 degrees C and a mass of 350g (specific heat of milk= 4200 J/kgK). no heat is lost to the bowl or the air as the banana and milk reach equilibrium. what is the equilibrium temperature of the banana and milk?
