A teacher opens up a window on a cold day. Which statement explains why the rooms starts to feel cold cool
when the teacher opens the window?
1. When the window is opened, cold air from outside enters the room, decreasing the room's temperature. The cold air mixes with the warm air in the room, leading to the room feeling cooler.
2. The open window allows heat to escape from the room. Heat transfers from the warmer room to the colder outside environment, making the room feel cooler.
Either of these statements can explain why the room starts to feel colder when the window is opened on a cold day.
