Yes, heat can attract dust. When the air is warm, it becomes less dense and rises, causing air currents to circulate. These air currents can pick up dust particles and carry them through the air. Additionally, warm air can cause surfaces to expand and create small air currents that can lift and carry dust particles. Therefore, heat can contribute to the movement and circulation of dust in the environment. **
