Two cylinders of equal capacity are connected to each other via stop cock. contains an ideal gas at a standard temperature and pressure, is completely evacuated. The entire system is thermally insulated. The stop cock suddenly opens. Which one is correct option?
View answer and explanation
Correct option: D
Change in internal energy is zero
Option D (Change in internal energy is zero) is correct because in free expansion against vacuum, no work is done, and for an ideal gas, internal energy depends only on temperature.
