Quick question!
A new kind of balloon is designed to be a perfect cube in shape, no matter how full. Suppose of these balloons can be stretched to a maximum surface area of 1435 cm2. The balloon is filled with 2.87 L of helium gas at a pressure of 746 torr and a temperature of 298 K. The balloon is then allowed to rise in the atmosphere. If the atmospheric temperature is 260 K, at what pressure will the balloon burst?
