Problem- A little boy on the beach lets go of a He filled balloon which floats up into the sky. The balloon finally pops after reaching a height of 1250. m above the ground where the temperature is 18 °C and the pressure is only 0.860 atm.
If the balloon was originally 3.50 L, how big was the balloon right before it popped? Assume the conditions on the beach were 27 °C and 1.00 atm.
Solve the above problem and provide steps with explanation
