Agas at 255 kilopascals and 45°c has an initial volume of 2.00l. the pressure of the gas increases to 805 kilopascals as the temperature is raised to 255°c. what will be the new volume?
1.05 liters
2.28 liters
1.25 liters
0.44 liters
1.50 liters

Answer : The correct option is, (a) 1.05 liters

Solution :

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 = 255 kpa

= final pressure of gas = 805 kpa

= initial volume of gas = 2 L

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get the final volume of gas.

Therefore, the final or new volume of gas will be, 1.05 liters
