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
