Question

What is the average kinetic energy of 1 mole of gas at 102 degrees celsius?

Answer 1

Answer: 4676.6 Joules

Step-by-step explanation:

Kinetic energy is the energy possessed by an object by virtue of its motion.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

`K=(3nRT)/(2)`

K= kinetic energy

n= number of moles of gas= 1

R= gas constant =8.314 J/Kmol

T= temperature in Kelvin =
`102^0C=(102+273)K=375K`

`K=(3* 1* 8.314* 375)/(2)=4676.6J`

Thus Kinetic energy will be 4676.6 Joules.

Answer 2

\[KE _{ave} = (3/2) R T\] R= 8.314 J/mol K T= 273 + 102 = 375K \[KE _{ave}\] = (3/2) x 8.314 x 375 = 4680 J/mol
