The answer is pressure. Pressure is characterized as drive per unit region. It is generally more advantageous to utilize weight instead of constraining to portray the impacts upon liquid conduct. The standard unit for weight is the Pascal, which is a Newton for every square meter.
The coorrect answer is option A. The pressure of the gas can cause the ideal gas constant R, to take dfferent values. Because all the other three factors namely, Temperature (T), Volume(V) and the number of moles (n) can change the pressure of a gas. So, I f we change the pressure of the gas alone, we can change its gas constant R value.
