The specific heat capacity of water is:

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

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

$$n \ moles$$ of gas an ideal monatomic gas is confined in a cylinder A of volume $$V_{0}$$, pressure $$P_{0}$$ and temperature $$T_{0}$$, 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 7$$V_{0}$$ and B is evacuated and then stopcork is opened so that gas expands and occupies the volume $$8V_{0}$$. [System is thermally isolated from the surroundings].

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

Water of mass $$m_2$$ = 1 kg is contained in a copper calorimeter of mass $$m_1$$  = 1 kg. Their common temperature t = $$10^{0}C$$. Now a piece of ice of mass $$m_3$$  = 2 kg and temperature is $$-11^{0}C$$ dropped into the calorimeter. Neglecting any heat loss, the final temperature of system is. [specific heat of copper = 0.1 Kcal/ kg$$^{0}C$$, specific heat of water = 1 Kcal/kg$$^{0}C$$, specific heat of ice = 0.5 Kcal/kg$$^{0}C$$, latent heat of fusion of ice = 78.7 Kcal/kg]

Specific heat of a gas undergoing adiabatic change is

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

Specific heat may be defined as:

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