Mr. and Mrs. Brennick open several windows to cool off their home. After a few minutes, they close the windows. They measure the temperature, and it is 5°C cooler than it was before they opened the windows. Which statement below best explains why that happened?

• The outside air added cold to the air in the room.

• The air particles in the room transferred kinetic energy to the air particles from outside.

• The air particles mixed so now all the air particles have less kinetic energy.

• The outside air particles added kinetic energy to the air particles in the room
