a balloon containing 600 cm3 cubed of a at a pressure of 0,828 kPa escaped from a child's hand in a shopping centre it rises and when it reaches the roof the volume has increased to 700 cm3 calculate the pressure of the balloon at this height assume that the temperature in the shopping centre remains constant

Answer:
≈ 0.70kPa
Explanation:
PV/nT = constant
P initial= 0.828kPa
P final = ?
V initial = 600cm³
V final = 700cm³
n initial = n final = n
Temperature initial = temperature final = T
So that
(P initial × V initial)/nT = (P final × V final)/nT
600 × 0.828 = 700 × P
P ≈ 0.70kPa
