← ScienceWhich mechanism causes pressure changes within sealed aerosol cans exhibiting elevated temperatures?
A)Thermal molecular kinetic energy increase✓
B)Increased van der Waals attraction
C)Partial pressure phase equilibrium shifts
D)Decreased propellant vaporization enthalpy
💡 Explanation
Increased temperature causes higher molecular kinetic energy, with increased speed and collisions, forcing gas particle pressure. Therefore, higher temperature leads to increased can pressure, rather than increased intermolecular forces or modified phase equilibria, because molecular motion dominates.
