Transfer of Thermal Energy

Which of the following best explains the scenario below? On a summer morning, Ayleen walks barefoot across her paved driveway with no problem. However, later that afternoon she steps barefoot onto the same driveway and must quickly run off because the bottoms of her feet feel like they are burning.

• As the temperature increased during the day, the particles in the pavement moved slower and the thermal energy increased.
• As the temperature increased during the day, the particles in the pavement moved slower and the thermal energy decreased.
• As the temperature increased during the day, the particles in the pavement moved faster and the thermal energy increased.
• As the temperature increased during the day, the particles in the pavement moved faster and the thermal energy decreased.
