When two small bubbles join to form a bigger one, energy is
Text Solution
Verified by ExpertsThe correct answer is:
A
Explanation:
When two small bubbles merge to form a larger bubble, there is a change in surface area that results in energy dynamics involving the surface tension of the bubbles.
When two small bubbles merge to form a larger bubble, there is a change in surface area that results in energy dynamics involving the surface tension of the bubbles.
- The process of merging two bubbles results in a decrease in total surface area. Smaller bubbles have a higher energy state due to their larger surface area relative to their volume. When they combine, the new, larger bubble has a smaller surface area to volume ratio.
- As two bubbles combine, the excess surface energy associated with the smaller bubbles is released. This release of energy is primarily due to the work done against surface tension. Thus, energy is released during the merging process.
