The air in a 2 L balloon at 0.998 atm and 34.0 °C. What will be its pressure if it is brought to a higher altitude where it now occupies 3.5 L and is at 12.0 °C?

0.529 atm

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 = 0.998 atm

= final pressure of gas = ?

= initial volume of gas = 2 L

= final volume of gas = 3.5 L

= initial temperature of gas =

= final temperature of gas =

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

Thus the pressure if it is brought to a higher altitude where it now occupies 3.5 L and is at 12.0 °C is 0.529 atm

i do not get it   at all

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
