An empty pressure cooker of volume 10 littee contains air at atmospheric pressure 10^5 pascal and temp of 27°C.It contains a whistle which has area of 0.1 cm^2 and weight of 100 gn .what should be temp of air inside so that the whistle is just lifted up.

Question

Arun · Answer

Pressure by whistle = P o + F / A = P o ​ + mg/ A = 10 5 Pa + (0.1 * 10 N) / (0.1 * 10 4 m 2 ) = 2 * 10 5 Pa Pressure inside cooker = 10 5 Pa for whistle to just lift, by gay lussacs law P whistle / T surrounding = P cooker / T cooker (2 * 10 5 Pa) / 300 K = 10 5 Pa / T T = 600 K = 327 o C
