Suppose that a cup of soup cooled from 90C to 60C after 10 minutes in a room whose temperature was 20C. Use Newton's law of cooling to ans a. How much longer would it take the soup to cool to 45C? b. Instead of being left to stand in the room, the cup of 90C soup is put in the freezer whose temperature is -5C. How long will it take the soup to a. How much longer would it take the soup to cool to 45C? min (Round the final answer to two decimal places as needed. Round all intermediate values to five decimal places as needed.)
