A balloon is launched when the temperature is 15 oC and the pressure is 0.918 atm. Its volume is 11.1 L. It rises in the air unt
ivann1987 [24]

Answer:

The new volume is 7,606.96 Liter.

Explanation:

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas in the balloon = 0.918 atm

P_2 = final pressure of gas in the balloon = 0.0012 atm

V_1 = initial volume of gas in the balloon = 11.1 L

V_2 = final volume of gas in the balloon = ?

T_1 = initial temperature of gas in the balloon = 15^oC=273+15=288K

T_2 = final temperature of gas in the balloon = -15^oC=273-15=258K

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

\frac{0.918 atm\times 11.1 L}{288 K}=\frac{0.0012 atm\times V_2}{258 K}

V_2=\frac{0.918 atm\times 11.1 L\times 258 K}{288 K\times 0.0012 atm}

V_2=7,606.97 L

The new volume is 7,606.96 Liter.

How would you convert 5 decades to months
katen-ka-za [31]
First, find out how many years are in a decade. There 10 years per decade. So in 5 decades, that makes 50 years. Then multiply 50×12 because there are 12 months in a year. So there are 600 months in 5 decades.

How are energy storage molecules affected if there is LESS carbon dioxide?
kipiarov [429]

Answer:

When there is less carbon (in the form of carbon dioxide) in abiotic matter, less carbon is available for producers making energy storage molecules. When there is more sunlight, producers can make more energy storage molecules from the carbon in carbon dioxide.

Hope this helps.
