5. Temperatures of upper and lower surfaces of a plane horizontal sheet of area S are maintained at T and T2 respectively. Air pressure on both sides of the sheet is po, the ambient temperature is To and acceleration of free fall is g. The air molecules strike a face of the sheet with kinetic energy that corresponds to the ambient temperature and bounce off the face of the sheet with kinetic energy that corresponds to the temperature of the face of the sheet. What should the mass of the shee be so that it stays floating at a level height in the air? S6.CTz-Tz)
