  • Question 1
    4 / -1
    The latent heat of vaporisation of water is 2240 J/g. If the work done in the process of expansion of 1 g is 168 J, then increase in internal energy is
    Solution

  • Question 2
    4 / -1
    A cylinder fitted with a piston contains 0.2 moles of air at temperature 27°C. The piston is pushed so slowly that the air within the cylinder remains in thermal equilibrium with the surroundings. Find the approximate work done by the system if the final volume is twice the initial volume
    Solution
