Question

The behaviour of a perfect gas, undergoing any change in the variables which
control physical properties, is governed by
1) pressure exerted by the gas 2) volume occupied by the gas
3) temperature of the gas 4) All of these

Answer 1

The behaviour of a perfect gas, undergoing any change in the variables which control physical properties is governed by :

(4) All of these (GAS LAWS)

Answer 2

Answer: The correct option (4).

Explanation:

According perfect ideal gas equation:

PV=nRT

p= pressure of gas in atm  (variable).

v= volume of gas in liters (variable).

n = number of moles of gas (variable).

R= universal gas constant (constant)

T= temperature of gas in kelvins (variable).

Hence, these four variables will control the physical properties of perfectly behaving gas.
