A. steam condenses and occupies the partial vacuum in the can
B. external air pressure counterbalances the pressure within the can
C. steam expands to occupy the vacuum remaining in the can
D. external pressure becomes greater than the pressure within the can.
Correct Answer:
Option D = external pressure becomes greater than the pressure within the can.
Explanation
Coldwater reduces the temperature of the hot water inside the can causing the contraction of the hot water. This reduces the pressure inside the can and the can collapses due to the external greater expression.
