Based on the physical properties, matter can be classified as _________.

Which of the following is liquid at ordinary temperature ?

 The weight is required to get 2.24 litre of oxygen at STP is :

10 gm of a gas at 1 atm and 273 K occupies 5 litres. The temperature at which the volume becomes double for the the mass of gas at the same pressure is :

26cc of $CO _2$ are passsed over red hot coke .The volume of CO evolved is :

At $0^o$C the density of nitrogen at $1$ atm is $1.25$ kg$/m^3$. The nitrogen which occupied $1500$ml at $0^o$C and $1$ atm was compressed at $0^o$C and $575$ atm and the gas volume was observed to be $3.92$ ml, in violation of Boyle's law. What was the final density of this non-ideal gas?

In an evacuated rigid vessel of volume V liter, one mole of solid ammonium carbonate, $ NH _2CONH _4 $ , is taken and the vessel is hated to T K. The equilibrium total pressure of gases is found to be P atm. The percentage dissociation of solid into $ NH _3(g) $ and $ CO _2 (g) $ is 

By what factor does water expand when converted into vapour at $100^o$C and $1$ atm pressure? The density of liquid water at $100^o$C and $1$ atm is $0.96$g $cm^{-3}$?

When water is cooled it contracts until it reaches ______ and then it starts expanding.

A solid shape has _____ dimensions and so occupies _______.
