A gas- filled freely collapsible balloon is pushed from the surface level of a lake to a depth of `100 m`. Approximately what percentage of its original volume will the balloon finally have? Assume that the gas behaves ideally

A gas filled freely collapsible balloon is pushed from the surface level of a lake to a depth of 50 m. Approximately what per cent of its original volume will the balloon finally have, assuming that the gas behaves ideally and temperature is same at the surface and at 50 m depth ?

A balloon filled with an ideal is taken from the surface of the sea deep to a depth of 100 m. What will be its volume in terms of its original volume ?

A block is falling in a lake at a depth of 100 m shows 0.2% decrease in its volume at the bottom. What is the bulk modulus of the block ?

A gas in a closed, flexible container is slowly cooled from 50^(@)C to 25^(@)C . What is the ratio of the final volume of the gas to its initial volume? (Assume ideal behaviour).

A mass of ideal gas at pressure P is expanded isothermally to four times the original volume and then slowly compressed adiabatically to its original volume. Assuming gamma to be 1.5, the new pressure of the gas is

A helium filled balloon had a volume of 400 ml, when it is cooled to -120^(@)C . What will be its volume if the balloon is warmed in an overn to 100^(@)C assuming changes in pressure.
