THERMODYNAMICS 1 / 5 Considering entropy(S) thermodynamic parameters the criteria for the spontaneity of any process is: △S system + △S surroundings > 0 △S system – △S surroundings < 0 △S system > 0 △S surroundings > 0 The criteria for the spontaneity of any process is△S system + △S surroundings > 0 2 / 5 The least random state of the water system is: ice liquid water steam randomness is same The least random state of the water system is ice. 3 / 5 For an ideal gas, CV and CP are related as : CV – CP = R CV + CP = R CP – Cv = RT CP – Cv = R For an ideal gas, CV and CP are related as CP – Cv = R 4 / 5 For the reaction C(s) + O2(g) → CO2(g) △H >△U △H < △U △H = △U None of these Here △ng RT = 0 , because reactant and product contain same number of gaseous molecules. So that △H = △U + △ng RT ⇒ △H = △U 5 / 5 A well stoppered thermos flask contains some ice cubes.
