                                                                                                         o
                      3.7  The pressure of the gas inside an aerosol can is 1.2 bar at a temperature of 25  C.
                            Will the aerosol explode if it is thrown into a fire and heated to a temperature of

                                o
                            600  C? Assume that the aerosol can is unable to withstand pressure in excess of 3
                            bar.


                                                        o
                      3.8  0.05 kg of air, initially at 130  C is heated at a constant pressure of 2 bar until the

                            volume occupied is 0.0658 m . Calculate the heat supplied and the work done.

                                                                                 3
                      3.9  A  spherical  research  balloon  is  filled  with  420  m   of  atmospheric  air  at  a

                            temperature of 10  C. If the air inside the balloon is heated to 80 C at constant
                            pressure, what will be the final diameter of the balloon?
