Question

A neutron is ejected from the sun with an energy of 1.50 TeV (T is the prefix tera, and eV is an electron-volt, a unit of energy). The neutron is stopped in a detecting tube that contains 0.150 mol of neon gas. Once this energy is distributed among all of the gas particles, by how much will the gas temperature have increased?

Answer 1

Change in temperature is given by following equation

Where n is no of moles of gas

R is gas constant = 8.314 J /(mol-K)

& E = 1.50 TeV = 1.5 x 1.6 x 10^(-7) J

= 2.40 x 10^(-7) J

Therefore

= 1.28 x 10^(-7) kelvin

This is the amount by which temperature of gas will increase.
