Correct option is A
The behavior of a gas is typically described using the
gas laws, which involve the following variables:
Pressure: A key variable in gas behavior, influencing how gases expand, compress, or exert force.
Volume: Another fundamental variable describing the space occupied by the gas.
Temperature: Essential for understanding the energy and motion of gas molecules.
Time is not a variable that directly describes the behavior of a gas, as it does not appear in equations like the ideal gas law:
PV=nRT
