4. The external pressure has to be equal to the internal pressure of balloon, because at equal pressure the forces will be in equilibrium and the volume of balloon will be constant.
5. When we blow into the balloon, the volume change but not the pressure , it is because the Walls of the balloon are not rigid, rather they can move , so the balloon always try to maintain the equilibrium between the external pressure and the internal pressure, hence the volume chsnges and not the pressure.
But in case of a non movable rigid wall system the pressure will increase and not the volume.

A compound vessel is obtained by shrinking an external cylinder of internal diameter equal to 200 mm and external diameter equal to 300 mm over a cylinder of internal diameter equal to 150 mm and external nominal diameter equal to 200 mm. Both cylinders are made of steel (E 205 Gpa) and an interference equal to 0.15 mm is used at the mating surface Calculate the radial and circumferential stresses at the inner and outer surfaces of the two cylinders,...

Imagine you have a balloon that you want to blow up, at a pressure of 2x10^5 Pa from a volume of 5.0 L to 10 L. How much work in kJ will be required? If you finish this in 10 seconds, what is your power (in watts)?

A helium-filled balloon at 1.00 atm pressure has a volume of 1.200 L. It is placed in a freezer and its volume decreases, stopping at 1.010 L. (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.) Calculate ΔE for the gas in the balloon.

A helium-filled balloon at 1.00 atm pressure has a volume of 1.320 L. It is placed in a freezer and its volume decreases, stopping at 0.990 L. (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.) Calculate ΔE for the gas in the balloon.

The compliance of a flexible structure, such as a balloon, is determined by a curve (volume vs. pressure), rather than being constant. As you inflate a balloon, it gets more and more difficult to achieve a given change in volume. Stated another way, you have to supply a greater change in pressure to achieve a given change in volume when the balloon is at higher volumes vs. when it is at lower volumes. This means that the compliance of the...

A toy balloon has an internal pressure of \(1.05\) atm and a volume of \(5.0 \mathrm{~L}\). If the temperature where the balloon is released is \(20^{\circ} \mathrm{C}\), what will happen to the volume when the balloon rises to an altitude where the pressure is \(0.65\) atm and the temperature is \(-15^{\circ} \mathrm{C} ?\)

Distinguish between the external return to scale and internal return to scale. How does the new trade theory of economic returns to scale differ from the traditional trade theories like Ricardian model, and Heckscher - Ohlin model? 3. 4. What is the Rybczynski theorem? How does theorem predict changes in factors usage in production and change in trading volume if there is an influx of immigrant?
