How much internal energy Eint is in the air in a 10 m *10 m * 10 m room at standard temperature and pressure? ( answer: 2.5 * 108 J)

Solutions

Expert Solution

Here, internal energy Eint is in the air   = 5/2 * nRT

                                                              = 5/2 * PV

                                                              =   5/2 * 1.013 * 105 * (10 * 10 * 10)

                                                                = 2.5 * 108 J
