    1 / -0

    The specific heat capacity of water is:

  • Question 2
    1 / -0

    Which of the following sets represent the normal physical states of the elements concerned at 25C25^{\circ}C and one bar pressure, with ΔH\Delta H^\circ (formation)=0=0

  • Question 3
    1 / -0

    Which of the following are not state functions?
    (I) q+wq+w 

    (II) qq
    (III) ww 
    (IV) HTSH-TS

  • Question 4
    1 / -0

    n molesn \ moles of gas an ideal monatomic gas is confined in a cylinder A of volume V0V_{0}, pressure P0P_{0} and temperature T0T_{0}, this cylinder is connected to another cylinder B with the help of tube of a negligible volume. The cylinder B is fitted with a movable piston which can be adjusted from outside. Initially, the piston is adjusted so that volume of B is 7V0V_{0} and B is evacuated and then stopcork is opened so that gas expands and occupies the volume 8V08V_{0}. [System is thermally isolated from the surroundings].


    During this free expansion, the internal energy of the system

  • Question 5
    1 / -0

    A sample of oxygen gas expands its volume from 3 L to 5 L3\ L\ to\ 5\ L against a constant pressure of 3 atm3\ atm. If work done during expansion is used to heat 10 mole of water initially present at 290 K290\ K, its final temperature will be (specific heat capacity of water = 4.18 J/kg):

  • Question 6
    1 / -0

    Water of mass m2m_2 = 1 kg is contained in a copper calorimeter of mass m1m_1  = 1 kg. Their common temperature t = 100C10^{0}C. Now a piece of ice of mass m3m_3  = 2 kg and temperature is 110C-11^{0}C dropped into the calorimeter. Neglecting any heat loss, the final temperature of system is. [specific heat of copper = 0.1 Kcal/ kg0C^{0}C, specific heat of water = 1 Kcal/kg0C^{0}C, specific heat of ice = 0.5 Kcal/kg0C^{0}C, latent heat of fusion of ice = 78.7 Kcal/kg]

  • Question 8
    1 / -0

    A liquid boils at such a temperature at which the saturated vapour pressure, as compared to atmospheric pressure, is 

  • Question 9
    1 / -0

    Specific heat may be defined as:

  • Question 10
    1 / -0

    The temperature at which the reaction AgO(s) Ag(s)+12O2(g)AgO(s)  \rightarrow Ag(s) + \frac{1}{2} O_2(g) is at equilibrium is?
    Given  ΔH=30.5 KJ mol1\Delta H = 30.5  KJ  mol^{-1} and Δ S=0.066KJK1 mol1\Delta  S = 0.066 KJK^{-1}  mol^{-1}
