Answer:
To determine the final temperature needed to cause the volume of the gas to change from 4.00 L to 50 L, we can use Charles's Law. Charles's Law states that for a given amount of gas at constant pressure, the volume of the gas is directly proportional to its temperature in Kelvin. The law can be expressed as:

where
1

and

V

are the initial and final volumes, respectively, and

and

are the initial and final temperatures, respectively.
Given:

First, we need to convert the initial temperature from degrees Celsius to Kelvin. The Kelvin temperature scale can be obtained by adding 273.15 to the Celsius temperature:

Thus, the final temperature needed to cause the volume of the gas to change to 50 L is approximately
