Excess Pressure in Soap Bubbles
JEE Main asked Excess Pressure in Soap Bubbles 6 times in 6 of the 108 shifts Lumi analysed, in 2020, 2022, 2024 and 2025. It belongs to Surface Tension, in Mechanical Properties of Fluids (Physics). The longest wait between two years asking it was 2 years. In 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year
2017–2026. Asked in 2020, 2022, 2024 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
Raw count: 2017: 0 in 1 shift · 2020: 1 in 12 shifts · 2021: 0 in 24 shifts · 2022: 1 in 24 shifts · 2023: 0 in 12 shifts · 2024: 3 in 18 shifts · 2025: 1 in 8 shifts · 2026: 0 in 9 shifts.
