From this paper
An incompressible gas in the cylinder of 15 cm diameter is used to support a piston. Manometer indicates a difference of 12 cm of Hg column for the gas in cylinder. Estimate the mass of piston that can be supported by the gas. Take density of mercury as 13.6 × 103 kg/m3. Notice: Known (1 mark), Find(1 mark), Schematic(1 mark), Assumptions(2 marks), Analysis(2 marks), and Comments(1 mark).
- 1.
Define the first law of thermodynamics. Also give supporting mathematical expression for it (2 marks).
