A closed weather balloon with an initial volume V rises up in the atmosphere to a point where the outside air pressure is 1/10 o
f the pressure at sea level and the temperature of the air has dropped by a factor of 3. Assume that the balloon is filled with an ideal gas and that the material of the balloon exerts no pressure and does not insulate so that the temperature and pressure are the same inside and outside the balloon. Do the volume and internal energy of the gas increase, decrease, or stay the same as the balloon rises? Justify your answer.
It's a circuit wherein all the elements are in parallel and a resistance is fitted in series across which a voltmeter is connected to measure potential drop acrossR so as to find the current across the load that is bulb which connected to in series with the resistor
