The discussion centers on calculating the net force on each side of a cubic metal box containing air at 1 atm and heated from 300K to 400K. Utilizing the ideal gas law, specifically the relationship \( \frac{P_2}{P_1}=\frac{T_2}{T_1} \), participants confirm that the pressure increases with temperature while volume remains constant. The net force on each side can be determined by applying the formula for pressure, which is defined as force divided by area. Thus, understanding the changes in pressure due to temperature variations is crucial for calculating the net force exerted on the box's sides.
