Question

Calculate the kinetic energy of 4 moles of methane at -73degree

Answer 1

Answer: 9977 Joules

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system.

Kinetic energy is the energy possessed by an object by virtue of its motion.It is determined by the equation:

$K.E=\frac{3nRT}{2}$

n= no of moles = 4

R= gas constant = 8.314 J/Kmol

T= temperature in Kelvin =$-73^0C=(273-73)=200K$

$K.E=\frac{3\times 4\times 8.314\times 200}{2}$

$K.E=9977Joules$
