Ah, for exam, you just remember physisorption is weak like van der Waals, and chemisorption is strong like a chemical bond. But real life? My old Bullet's engine – when a little oil sticks to the piston wall, that's weak, temporary. But when carbon gets baked onto it, that's a strong bond, and it's a problem. That stubborn carbon deposit is like chemisorption – won't come off easy, gives me constant tension. Schoolbook answer is for marks, but my bike’s trouble is for life.
