Suppose that a cup of soup cooled from 90°C to 70°C after 10 minutes in a room whose temperature was 20°C. Use Newton's law of cooling to answer the following questions. a. How much longer would it take the soup to cool to 50°C? b. Instead of being left to stand in the room, the cup of 90°C soup is put in the freezer whose temperature is - 20°C. How long will it take the soup to cool from 90°C to 50°C?
