Interpretation Introduction

Interpretation:

The statement “when a car accelerates quickly the passengers feel a force that presses them back into their seats but balloon filled with helium floats forward” is to be explained.

Concept introduction:

The ideal gas equation can be expressed as follows,

  $PV=nRT$

Here, $P$ is the pressure, $V$ is the volume, $T$ is the temperature, $n$ is the mole of the gas and $R$ is the gas constant.

The pressure is defined as the force acting over a unit area. The movement of gas occurs from high pressure to low pressure.
