Choose the correct option for the following Assertion (A) and Reason (R).

Question

G1 Physics · Accepted Answer

For a soap bubble, ΔP = 4S/R. Therefore, smaller R → greater internal excess pressure. When a smaller and larger bubble are connected, gas initially flows from the higher-pressure smaller bubble to the lower-pressure larger bubble. Thus the smaller bubble tends to shrink. Both Assertion and Reason are true, and the Reason correctly explains the Assertion. Correct option: A.
