The pressure inside a gas bottle is 4120 kPa when the temperature is 29.0 °C. What will be the pressure inside the bottle, if 34.9 percent of the gas is released and the temperature of the gas drops to 5.5 °C?

The pressure inside the bottle is 2473 kPa

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law, Avogadros law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas = 4120 kPa

= final pressure of gas = ?

= initial volume of gas = v

= final volume of gas = v

= initial moles of gas = n

= final moles of gas =

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get:

Thus the pressure inside the bottle, if 34.9 percent of the gas is released and the temperature of the gas drops to 5.5 °C is 2473 kPa

are their multiple choices ?

explanation:

technology is the application of the knowledge gained by science.
