Question

A gas filled weather balloon in the atmosphere has an initial volume of 850L. The weather balloon rises to a region where the pressure is 56 kPa (56,000 Pa), and its volume expands to 1700 L. If the temperature remains the same, what was the initial pressure on the weather balloon?

Answer 1

112 kPa

Step-by-step explanation:

Ideal gas law:

PV = nRT

Since the amount of gas and temperature remain constant:

P₁V₁ = P₂V₂

P (850 L) = (56 kPa) (1700 L)

P = 112 kPa
