Answer: The new temperature is 10643 K
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 750.0 mm Hg = 0.98 atm (760mmHg=1atm)
= final pressure of gas = 3.50 atm
= initial volume of gas = 2.00 L
= final volume of gas = 20.0 L
= initial temperature of gas =
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
Thus the new temperature is 10643 K
