The average Kinetic energy of the argon atoms is 6.13×10⁻¹⁹ J.

Average kinetic energy:

The average kinetic energy of a particle is directly proportional to the temperature of the particle.

To calculate the average kinetic energy of the argon atoms, we use the formula below.

Formula:

  • K.E = 3KT/2.............. Equation 1

Where:

  • K.E = Average Kinetic Energy of the argon atoms
  • K = Boltzmann's constant
  • T = Temperature.

From the question,

Given:

  • T = 115°F = 319.261 K
  • K = 1.381×10⁻²³ J/K

Substitute these values into equation 1

  • K.E = 3(319.261)(1.281×10⁻²¹)/2
  • K.E = 613.46×10⁻²¹ J
  • K.E = 6.13×10⁻¹⁹ J

Hence the average Kinetic energy of the argon atoms is 6.13×10⁻¹⁹ J.
