A well stoppered thermos flask contains some ice Cubes. This is an example of a 

Identify the intensive quantity from the following.

A system has internal energy equal to ${\mathrm{E}}_1,450 \mathrm{J}$ of heat is taken out of it and $600 \mathrm{J}$ of work is done on it. The final energy of the system will be -

The difference between heats of reaction at constant pressure and constant volume for the reaction,

$2{\mathrm{C}}_6{\mathrm{H}}_6 \left(\mathrm{l}\right)+15{\mathrm{O}}_2 \left(\mathrm{g}\right) \to 12{\mathrm{CO}}_2 \left(\mathrm{g}\right) + 6{\mathrm{H}}_2\mathrm{O} \left(\mathrm{l}\right)$ at $25°\mathrm{C}$ in $\mathrm{kJ}$ is:

One mole of a gas occupying $3 {\mathrm{dm}}^3$ expands against a constant external pressure of $1$ atm to a volume of $13$ lit. The workdone is :-

The total entropy change for a system and its surrounding increases, if the process is

Enthalpy of a compound is equal to its. (When it is formed from constituent particles)

If ${\mathrm{H}}^{+}+{\mathrm{OH}}^{-}\to {\mathrm{H}}_2\mathrm{O}+13.7 \mathrm{kcal}$, then heat change of complete neutralisation of one gram mole of ${\mathrm{H}}_2{\mathrm{SO}}_4$ with strong base will be:
