It is desired to increase the volume of a given weight of co2 at40degrees to three times original volume at constant pressure the temperature should be raised a) 333b) 120c) 666 degrees?
The answer is option
Apply Charles' Law
The initial volume is
The final volume is
The initial temperature is
The final temperature is
The temperature should be raised by
According to the problem, pressure remains constants. Since the weight also is constant, the number of moles remains constant.
From the ideal gas equation, we can deduce that
