Final answer:
Foam weather stripping reduces heat loss due to convection.
Step-by-step explanation:
Foam weather stripping placed in the frames of doors and windows in a home has the effect of reducing heat loss due to convection. As mentioned in the given information, air acts as a poor conductor and a good insulator. The weather stripping prevents airflow, creating a barrier that reduces heat transfer by convection. This helps to keep the temperature inside the home more stable and reduces energy costs.
