A weather balloon is filled with helium that occupies a volume of 500 L at 0.995 atm and 32.0 ℃. After it is released, it rises
Yuki888 [10]

Answer : The volume of the balloon at the new location is, 591.3 L

Explanation :

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

The combined gas equation is,

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

where,

P_1 = initial pressure of gas = 0.995 atm

P_2 = final pressure of gas = 0.720 atm

V_1 = initial volume of gas = 500 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 32.0^oC=273+32=305K

T_2 = final temperature of gas = -12^oC=273+(-12)=261K

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

\frac{0.995atm\times 500L}{305K}=\frac{0.720atm\times V_2}{261K}

V_2=591.3L

Therefore, the volume of the balloon at the new location is, 591.3 L

what is the realtionship between the kentic energy of molecules in an object and the objects tempeture
MrMuchimi
Temperature is a measure of the average kinetic energy of the particles in an object .Temperatures also measure how kinetic energy is not how hot or cold it is. It’s measuring what the amount of Kinetic Energy there when you throw something in the air and it comes back down
