The answer is option
Explanation:
Apply Charles' Law
The initial volume is
The final volume is
The initial temperature is
The final temperature is
Therefore,
The temperature should be raised by
Using
Explanation:
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
So
