Answer:
The value of maximum pressure the balloon could be filled = 6.40 atmosphere.
Explanation:
When helium from the cylinder is filled inside the balloon the heat & work
transfer is zero during the process. so from the first law of thermodynamics
change in internal energy is zero.
⇒ = 0
⇒ =
⇒ =
------------- (1)
Final temperature is equal to initial temperature.
Equation (1) can be written as
⇒ =
-------------(2)
Initial volume = 44 L
Final volume = 296 L
Initial pressure = 43.1 atmosphere
Final pressure = we have to calculate
Put all the values in Equation (2) we get,
⇒ × 296 = 43.1 × 44
⇒ = 6.40 atmosphere
This is the value of maximum pressure the balloon could be filled.
