Exposed ceiling beams are popular in many modern houses. however, because they are exposed, their ignition in the event of a fire is of concern. consider a 15 cm by 15 cm yellow pine beam, initially at 25°c, attached to a ceiling, thus insulat- ing the base. the three other sides are exposed to fire at 600°c with a combined convective/radiative heat transfer coefficient of 50 w/m2.k. determine the beam's maximum temperature 5 min after fire starts.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
