1) 150 g of a liquid at 45ºC is filled in an insulated metal container at 35°C whose mass is 110 g. The system eventually reaches an equilibrium. Find: (a) the final equilibrium temperature, and (b) estimate total change in entropy of the system (i.e. metal container plus liquid) . Specific heat of liquid is 4186 J/kg . Cº and specific heat of metal is 900 J/kg. C°. [5 pts]
