Estimate the total amount of translational kinetic energy in a small classroom at normal room temperature. Assume the room measures 5.00 m by 12.0 m by 4.00 m.

2 answers

The translational kinetic energy in a room containing N moles is
Etran = (3/2)N*R*T,
where T = 293 K. Get the number of moles, N, from the volume and the ideal gas relation

N = P*V/(R*T)

Since V = 240 m^3 = 240*10^3 liters
N = 1.0*10^4 moles

Take it from there
Thank you so much!
