Question

The gas law PV/T= constant is true for
(a) isothermal changes only
(b) adiabatic changes only
(c) both isothermal and adiabatic changes
(d) neither isothermal nor adiabatic change

Answer 1

Answer:

(c) both isothermal and adiabatic changes

Answer 2

The right response to the given question is option c: both isothermal and adiabatic changes.

• From the gas law for ideal gaseous matter, the pressure on the gas, the volume it has acquired in the system along its temperature are constant.
• There is no alteration in temperature across the system when an isothermal process shift occurs. The temperature stays invariable.
• 1/T = constant, according to the gas law equation. As a result, this legislation applies to isothermal process shifts.
• The adiabatic process change is one in which no amount of heat is transferred from and across the system and the outside environment.
• As a consequence, heat movement in such a closed system is nil. Therefore, this law is also correct for processes that are adiabatic.
• Hence, option c is the proper choice in this case since the law applies to both of the adjustments indicated in the choices.
