Final answer:

This detailed answer provides calculations for the temperature change in a room when an air conditioner is running.


Explanation:

Temperature Change Calculation:

  1. For a) After 6 min: 45°C - (4°C/min x 6 min) = 45°C - 24°C = 21°C
  2. For b) Time to reach 33°C: (45°C - 33°C) / 4°C/min = 3 minutes
