On the cold day, the smell reached the student with the stopwatch slower than on the warm day. What does this data provide evidence of?

• On a cold day, the molecules of gas in the room are lighter and move faster.

• On a cold day, more energy is transferred to the gas in the container.

• On a cold day, the molecules of gas in the room have less kinetic energy on average.

• On a cold day, less energy was needed to move the gas across the room.
