if the volume of the gas sample is decreased to 19.1 l holding the temperature constant, the number of molecule-wall collisions per unit area per unit time will

Sagot :

The number of molecule-wall collisions per unit are time will be the same as ideal gas law is applicable to ideal gases only.

The equation for ideal gas law is Pv = nRT. Ideal gasses are the perfect gases to follow idealism. Ideal gas equation is the mathematical expression that relates pressure, volume and temperature at the same time.

  Mathematically, Pv = nRT is,

P = Pressure of the gas

v = Volume of the gas

n = Number of moles

R = gas constant (0.0821 L.atm/K.mol)

T = Temperature of the gas.

    In the given condition, the volume of the sample is decreased to 19.1 liter keeping the temperature same. Therefore, the number of collisions per unit area remains constant for the given condition of the sample of gas.
