Riya's room has an air conditioner, an electric fan and a paper fan. She feels a bit hot but she does not want to waste electricity, then which one among the following options should she use?
Open the windows and use the paper fan
When the windows are opened there will be proper air ventilation which helps to reduce the hotness inside the room. Along with this, if a paper fan is used, it will provide better air circulation which makes that part of the room cold.
