Consider a closed rectangular chamber of dimensions 1 m x 1 m x 2.5 m with a circular lid on it of diameter, 2 cm. the air inside the chamber is at standard atmospheric conditions (pressure, p=1 atm, and temperature, t=25 c). (a) what is the mass of air inside the chamber (in kg)? then the chamber is heated to 2707 c. (b) what is the density inside the chamber (provided the lid remain closed)? (c) what is the pressure inside the change (in atm)? (d) what is the force applied on the lid by the trapped heated air (in n)?
