During which step in the can crush lab did the air pressure outside the can become greater than the pressure inside the can? . a. the can was filled nearly to the top with water.. b. the can was placed on the hot stove burner for several minutes.. c. the can was removed from the hot oven burner.. d. the can was placed upside-down in the water-filled pan.

The answer is D. Heating the air in the can reduces the air pressure in the can. When the can is inverted in a pan with cold water, the can collapses inwards. This is because the cold water cooled the air around the outside of the can. Cold air has a higher pressure that hot air because it’s denser. Became. The higher air pressure outside presses on the can walls and force them inwards.
