1hmm ... point...
A straight glass tube has sealed lower end and upper end open to atmosphere.The lower half is filled with n moles of diatomic gas .The length of the tube is 1.52 m
How much heat should be provided to the gas such that all the mercury is pushed out of the tube,given that
(Atm Pressure in SI units) * (Are of cross-section of tube ) * 0.76m = 16J
The answer given is 27 joules,how do you solve this?i was gettin 24J from a linear P-V plot
