Final answer:
Heat loss can be slowed down by using insulation to trap air and prevent convection and conduction, and by reducing airflow, such as with double-paned windows, which limits heat transfer away from the warm area.
Step-by-step explanation:
Two factors that can slow down heat loss are insulation and reduced airflow. Insulation, such as wall insulation or clothing, slows down heat loss by trapping air—a poor conductor—in small spaces, thereby reducing heat transfer through convection and conduction. For example, adding wall insulation prevents airflow between the inside and outside walls of a house, meaning less heat is lost. Moreover, materials like fur, feather, and fiberglass effectively trap air and impede heat flow. Similarly, reduced airflow, which can be achieved by double-paned windows with a narrow gap between the panes, prevents the air from moving and conducting heat away from the warm interior. Clothing also plays an essential role in reducing heat loss by inhibiting both conduction and convection, with dense, thick fabrics providing more heat retention.
