7. An old "trick" for cooling down a hot beverage quickly is to immerse a cold spoon into the liquid. A silver spoon weighing 3.20 oz and at a temperature of 20°C is placed in a cup of hot coffee (8.00 oz) at 70°C. What will be the resulting liquid temperature? Assume that specific heat of coffee is 4.18 J g-1 °C-1 and that of silver is 0.234 J g-¹ °C-1. Comment on the effectiveness of this method of cooling a hot drink. 1 g = 0.0352 oz
