An ideal gas in a balloon is kept in thermal equilibrium with its constant-temperature surroundings. How much work is done if th
e outside pressure is slowly reduced, allowing the balloon to expand to 50 times its original size

Answer:
w = 252.32 N 
Explanation:
given data 
balloon expand = 50 times its original size
we consider here  initially pressure and volume 
pressure = 645 pa 
volume = 0.10 m³
solution
as in isothermala process ideal gas 
PV = mRT 
P = 
P = 
here c is constant 
so work done is express as
 
   
w =  
 
and we know c  = p1 × v1 
so 
w = p1 × v1 × 
w = 645 × 0.1 × ln(50) 
w = 252.32 N
